| 31may07/ME: 1x2 was chipped during installation on a half-disk. The breakdown on the inner loop is now 350V (it was previously tested good). Grade was changed to B.
5June07/ RV/SM: Panel P4L_025 had 1x2 plaquette chipped. It may have happened in Lab C. Anyway, this panel came back as it was showing breakdown on the inner loop while on HD-Z4.
we did IV curve 1. on the whole panel (breaksdown around 460V acording to renaisance)and then 2. IV curve with 1x2 HV wirebond removed (does not breakdown according to renaisance). See elog entry 3911 for the plots. These plots are saved as root files in the file following files on fpixserv:
P_1x5R_014_C_PanelRun3_v_2_8_0_IV_20C.root and P_1x5R_014_C_PanelRun4_v_2_8_0_IV_20C_without_1x2.root |
