MKD Reliability run Viliam Senaj TCM meeting 18/11/2014
Tests performed on generators Since 01/10: – LBDS1: 11 ES up to 7.1 TeV (55 pulses at each energy) + ~ TeV + ~ TeV GeV – LBDS2: 14 ES up to 7.1 TeV (70 pulses) + ~ TeV – No real reliability run because of too high temperature at UA63/67 (VAC group maintenance) – Modification performed: Compensation voltage setting at low energies (up to 800 GeV) to make R_end curve more flat Increase of bias voltage to 280 V (from 270 V) in order to reduce R_1 at low energies (>7.5%)
Problems observed B2: 24 V PS inside PTU B2: 150 V PS inside PTU Compensation PS 4 kV PS inside PTU
Still to be done New ES; generating new settings, tracking limits… Reliability run…
