Title:

WP3: 00 Auger projectile spectroscopy - Design of experimental apparatus

Description:

Research Teams:

RT1, RT2, RT3

3.1 Design of full experimental setup inside collision chamber: Details of electron optics, gas cell and spectrometer input lens geometries will be reconsidered and partially redesigned to further improve Kansas apparatus. TRANSPORT code used to optimize ion beam transmission through the target gas cell.

3.2 Market research, ordering and receiving all required components: The apparatus from Kansas came without electronics such as signal processing amps, HV power supplies and data acquisition which have to be bought. New spectrometer support will be designed and constructed in the machine shop.  

Deliverables:

2 Reports and part of BS, MS or PhD thesis
