Description
The quality of slow extraction from the SPS (Super Proton
Synchrotron) to the North Area is critically influenced by
the straightness tolerance of the electrostatic septum. Past
observations have identified a degradation of the anode body
straightness, resulting in an increased beam loss during ex-
traction. A new metrology bench including optical sensors
has been developed to cope with the tolerance requirements
while also allowing process automation. Two distinct mea-
surement procedures are currently employed: one for the
anode noses and another for the individual wire metrology. A
control system was developed to automate the metrology and
analysis process, allowing operator and time-independent
measurements and increasing process accuracy. The find-
ings from these investigations provide accurate information
in case corrective machining of the anode body is required.
The metrology method and the described nose scan approach
will further reduce beam loss during the slow extraction pro-
cess.
