Beam-beam effect, or beam-beam interaction, is a recent research being conducted over many areas throughout the world, from European laboratories to American Institutes. Basically the issue involves the passing through of proton bunches which results in many different types of effect, sometimes including the unexpected. Aside from the shooting of particles across one another, usually the collision rate of the protons generates a certain amount of energy. Today, the issue is to focus on modifying new colliders to enhance the effectiveness of the machines.
The study of the beam-beam effect involves particle colliders which determines the collision rate of protons. One of the commonly used collider is the LHC, which stands for Large Hadron Collider. The LHC is an accelerator which brings protons and ions into collisions at higher energies than ever achieved before. This will allow scientists to penetrate still further into the structure of matter and recreate the conditions prevailing in the early universe, just after the "big bang". It is represented by a thick gaussian lens, and the ring is described by a 9th-order Taylor map. At the single-particle level we compare the dynamic aperture with and without the beam-beam effect. At the multiparticle level, using a "strong-strong" description of the beam-beam interaction, we compare the collision rate with a linear lattice map and with the full nonlinear map. The LHC is being used at CERN, the world's largest physics center for particle physics exploring what matter is made of, and what forces hold it together.
Many different models for this effect have been conducted before, but most of them often ignored longitudinal motions of the particles, meaning that they only look for steady-state solutions, or assumed one beam contained a larger number of particles. These are usually known as "weak-strong" simulations. The LHC being developed is a "strong-strong" simulation in that it treats both beams equally and allows them to have arbitrary relative strengths. It is dynamic in that it models the motion on a turn-by-turn basis looking for coherent oscillations in the beam shape. It uses a variety of methods for computing the electric fields so that it can run as quickly as possible in each situation it encounters.
Inside the LHC, usually there is a storage ring acting as accelerator that collide the bunches of particles repeatedly by storing the bunches in the collider throughout a certain amount of time. When shooting out the particles, the collider aims for a very high collision rate, or luminosity.
The characteristic scale of gravitational mi- crolensing is the radius of the Einstein ring RE. The Einstein ring occurs when lens and source are aligned and the light from the source is shaped into a ring through the gravitational lensing by the gravitational field of the ”lensing” ob- ject.
Traditionally men have dominated the world of sports however in recent year’s women’s sports have become popular and with their new found popularity, women’s sports have evolved into marketable leagues of their own. Although women’s sports took a huge leap forward, women players still don’t receive the same financial compensation for playing the same sports in the same arenas as their male counterparts. In Purse Snatching by Donna Lopiano, she points out sexism may have a huge effect on this financial discrepancy between women and men athletes. Analyzing sports economics may point to a different reason why women are receiving such a compensation disparity.

F. Scott Fitzgerald’s novel, The Great Gatsby can perhaps be argued to be one of the greatest American novels of the twentieth century. Almost a century a later, “It seems to find its way to the top of the lesson-plan book” (Dowling 109). There are a multitude of reasons that make this exceptional work of fiction immensely popular and adored many. Fitzgerald’s style of writing and creativity produce an original storyline with convoluted characters making this award winning novel a breathtaking work of art celebrated in almost every English class across the nation. The intricate construction of Gatsby 's character and relatable themes helps readers better comprehend the storyline and develop an emotional connection. Gatsby’s character is more
Men and women have been separated since the beginning of life. God put Adam in charge of the Earth. When God created Eve, he took a piece of Adam’s rib from his stomach to create Eve. From this story that came from the bible, men believe that God made them better than women. And this has created a gender inequality between man and woman ever since then. Gender inequality, as stated on The Free Dictionary’s website is, “the difference between women and men in regard to social, political, economic, or other attainments or attitudes, or the problem perceives to exist because of such difference.” I believe that, when it comes to women’s sports, there is a pretty big difference in genders. Some of these differences are caused by men. A good example is that there are an enormous amount of men that take it as a joke. Most men feel that women just do not have the capability to ever have the strength and skills to compete with men. While others look at it as women are too girly to play and that they will cry and complain if they break a nail. Some think women are too fragile and if they try to compete against a man they will get badly injured. I believe these opinions that men have about women in sports, leads to the gender inequalities in it.
During the birth of the new nation, the Founding Fathers sought to construct a system of checks and balances which were catalyzed by the common fear of tyrannical government and based upon the ideologies of the Enlightenment. In 1787, while the infant nation was wobbling on the weak footings of the Articles of Confederation, the Constitutional Convention was adjourned and disputes around power and representation mustered new plans for the future. Although the Convention intended to revise and rework the Articles, James Madison, alongside...

Well, another reason why there is no equality between women and men in sports is also because of the salary of women playing sports versus the men playing.
The nuclei are ejected from heavy, unstable nuclei so as to remove excess protons and neutrons. However, the formed nuclei may still be radioactive in which even further decay will occur. Alpha emissions occur in nuclei with atomic numbers greater than 83. E.g 23892U 42He + 23490Th (both mass and No. of protons are conserved during the reaction)
Operating the largest machine in the world won’t be essay. The collider has two functions, it is to accelerate particles to high speeds in a beam that is about 2mm wide and then to direct the beams to the heart of the collider, where the head-on collision takes place. The particles that the Hadron collider accelerates are protons and lead nuclei; these have positive charges and so can be steered by magnets. These super magnets (9,300 in total) are used to control and steer the particles as they make their way around the 27km loop of the Large Hadron Collider. The Hadron Collider actually has two beams which travel opposite to each other so two sets of protons can travel towards each other. At the heart of the collider, the two beams meet for a brief moment, and that’s where the things go bang! This is where the explosion takes place and where the scientist, can try to find new elements.
Overall, the differences between what male athletes and female athletes must do in order to become successful is vastly distinct. A woman must be able to cope with receiving a lower salary than a man, expose herself to public eye in order earn time in the spotlight, and conform to society’s traditionalistic ideals of feministic traits to live up to the standards of a female athlete. Will people ever be able to see past these discriminatory stereotypes? Everyone needs to face the fact that women are capable of so much more than what society expects them to be, sees them to be, and pays them to be. It is time that female athletes are noticed for their genuine talents and not for any unnecessary opinions.
...ration of proton is not possible with available laser intensity. Because of its heavy mass, acceleration up to MeV need more laser intensity to overcome relativistic threshold. Energetic ions observed in the laser-solid interaction have been accelerated not directly by the laser fields but by the plasma fields which are formed by the laser heated electrons formed from solid or gas. However, these plasma electrons can inter-mediate the forces of laser fields on ions by generating strong quasi-static electric fields which arises from the charge separation due to the laser propagation. To accelerate the ion or proton need strong enough static electric field which can be explained best in two scenarios. These scenarios are
...h cesium ions and then to focus it into a fast moving beam. The ions that are produced become negative, which helps prevents the confusion of Carbon-14 with Nitrogen-14 since Nitrogen does not have a negative ion. The first magnet is used to select ions with an atomic mass of fourteen. The ions then enter the accelerator. As they travel to the terminal, they are accelerated to an incredible speed so when they collide with the gas molecules, all of the molecular ions are broken up and most of the carbon ions have four electrons removed, turning them into Carbon3+ ions. The second magnet selects ions with the speed expected for the Carbon-14 ion and a filter makes sure their momentum is also right. Finally, the filtered Carbon-14 ions enter the detector where their speed and energy are checked so that the number of Carbon-14 ions in the sample can be counted (Oxford).
In essence, the Harvest Gypsies was written as a documentary elucidating on the lives of American immigrants into California in search of employment that would help feed their families. The low-income families would work for minimal wages as there were plenty of laborers in the town because of increased immigration. Despite the existence of high wages that could be received from employment for instance harvesting crops, the neighboring towns would not match the extent of labor supply in such a time. Understandably, this period was marked by great depression, affecting poor and rich individuals across the country (Steinbeck and Charles 1998). Due to such, the native poor had to migrate to other states, for instance, California,
Today, Mathematical Physics has gone far. Due to the rapid advancement and the presence of modern technology like computers, direct numerical method using computers to formulate mathematical models become more and more essential. Using new technologies, the process involved in the formulation of mathematical models becomes simpler and inexpensive.
