Jimenez Injection Study with train of 24 Bunches 10/10/10 – 15:00 Start increase pressure on both lines when the number of protons in the machine is about: Beam B=1E13 Beam R=8E12 Test Solenoid A4L1 T=40C = 6A Test Solenoid A4R1 T=40C = 8A Solenoid A4L1 - ONSolenoid A4L1 - OFF Solenoid A4R1 - ONSolenoid A4R1 - OFF DUMP

Temperatures on the TC: A4L1: CH 6= 26  C A4R1: CH 2= 24  C CH6= 26  C Stable beams should be guaranteed in order to have better indication of temperature increase
