# Tool to align the solenoid on the gun.
# S. Bettoni, A. Gobbo, D. Voulot
# 30/05/2016
# Procedure:
# switch off all the magnets between the gun solenoid and the screen or BPM used for the measurement
# change the current of the gun soleoid
# look at the centroid position (BPM or screen) downstream of the gun.
