Trying the LOCO

12h35 Modulator Interlocks at HV=1215V, Went to 1200 V. Did not help even at 1000V (Maher's intervention needed).

13h00 This is the problem with triggering. When triggered internally, the modulator is working.

13h07 OK at HV=1215 V (Unknown reason). Nikolas said miss triggering is less than 5%

13h20 Linac frequency was changed a little bit to diminish miss triggering
