The cryoprpbe was cooled down on Friday May 22, 2015. This time the cooldown/service took longer than usual as a filter pack had burst in the He supply line. The Cryobay was cleaned and the filterpack was removed from the supply line and reccoled. The coil heater is at 30% and preamp heater at 170%. The pulse widths have shortened by about 5% after service.
