Pulser walkthrough taken for motor position 23.1mm and motor position 67.43mm.
Points taken at 30,50,70,90,110,130,150,170,190,210,230 for 23.1mm position and 230,210,190,170,150,130,110 for 67.43mm position.
Motors moved to fully OUT position and pin put back in. Current positions before closing program 19.1mm and 19.57mm. |

|
02:25
Zoran was unable to ignite the ion source.
He has given some parameters to the control room so they can wiggle stuff around and try and ignite it. |
