3 TE-VSC Group J.M. Jimenez Solenoids between DFBX and D1 in IR1R Solenoid A4L1 - ON TE-VSC Group J.M. Jimenez

4 TE-VSC Group J.M. Jimenez Fill 1404 Injection Study with train of 24 Bunches 10/10/10 – 15:00

5 TE-VSC Group J.M. 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

6 TE-VSC Group J.M. Jimenez Injection Study with train of 24 Bunches 10/10/10 – 15:00 A4L1.XSTART (No beam – Solenoid OFF)Solenoid ONSolenoid OFF VGPB.7.4L1.X1.9E-102.7E-103.8E-9 VGPB.9.4L1.X1.3E-102E-102.7E-9 A4R1.XSTART (No beam – Solenoid OFF)Solenoid ONSolenoid OFF VGPB.7.4R1.X1.9E-102.7E-101.1E-9 VGPB.9.4R1.X3.9E-104.2E-109.2e-10 There was an expected dump of beams due to lost during injection, so the final pressure without the solenoid are lower than expected. 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
