description | As part of the CERN summer student program I participated in building a short hydrogen beamline. After completion of the assembly my work consisted of characterization of the beamline. A so-called chopper is used for modulating the beam in order to distinguish the beam from the background hydrogen in the vacuum chambers. This modulation is also used to measure the velocity of the beam via a Time-of-Flight (TOF) measurement. It was found that the extracted velocity is dependent on the driving voltage of the chopper. Upstream of the chopper a pair of permanent sextupoles is used for polarizing the beam and velocity selection. The effect of the relative separation of these sextupoles on the velocity distribution was also investigated as part of this report. |
