Q2Q option - last section (1 Viewer)

[grinnie]

for the last section on Q2Q, does anyone have any idea about what exactly we should know about particle accelerators? should we know how to explain how they work or just identify them, because Jacaranda book explains about 3 of them and the excel book explains like much more. any ideas??????????

the only dot point about particle accelerators in the new syllabus is this:

Identify ways by which physicists continue to develop their understanding of matter, using accelerators as a probe to investigate the structure of matter

so i guess u'd only need to know the general function of each type of accelerator (im doin particle, linear, cyclotron & synchrotron) and then expalin how these are used to investigate the structure of matter i.e. using particle accelerators to input energy into a nucleus.

the stability of a nucleus is determined by the value of the binding energy per nucleon... the larger the value the more stable the nucleus. to investigate the nuclear force and the nature of the fundamental particles, the nucleus needs to be disrupted. to do this energy must be put into the nucleus using particle accelerators to probe inside atoms.
particle accelerators produce beams of very high-energy particles. beams of very high-energy particles are useful matter probes for two main reasons. firstly, to disrupt the nucleus and secondly, the higher the energy (and therefore velocity) of a particle, the smaller the de broglie wavelength. the smaller the de broglie wavelength, the better the resolving power of a beam of such particles.
there are many different types of particle accelerator: the van de graaff accelerator used to accelerate protons, deuterons & a-particles; the cyclotron, synchro-cyclotron, synchrotron and linear accelerator used to accelerate a variety of charged particles; and the Betatron used to accelerate electrons.

basically, that's it.

thanx heaps!
