WP4: 0⁰ Collision chamber preparation

Description:

Research Teams:

RT1, RT2, RT3

4.1 Preparation of high vacuum collision chamber: Careful study of best usage of two collision chambers brought from Kansas. The 2^nd chamber is bigger than the original with more space for gas cell and spectrometer and has better mu-metal shielding advantages that need to be considered. High voltage cabling considerations. Electrical signal and noise pick-up considerations. Pumping speed analysis, selection of turbo pumps and ultimate vacuum considerations. Typically, a central turbo pump (350-500 lt/s) is needed for the chamber with a second smaller one (100 lt/s) for the target gas cell. All pumps will have to be bought.

4.2 Faraday cup construction: The Faraday cup has to be designed, built and carefully installed on the chamber. It is used to stop the beam and measure its current for monitoring and spectrum normalization.

4.3 Connection of chamber to beam line and final tests with ion beam from TANDEM: The whole chamber and Faraday cup will be tested for vacuum to about 1 x 10^-7 Torr. Then it will be connected to the beam line and aligned to the beam axis on a special support stand that will be built in the machine shop. Check of transmission and current integration with ion beam from the accelerator.
