MP3Preliminary Results of Quench Tests with Beam (14.02.-16.02.) D. Wollmann 05.03.2013
Quench tests with beam Goals: • Measure the quench limitsof sc. magnets with beam in different time scales and different realistic loss distributions.
Proton Collimation Quench testPreliminary Results • We achieved peak losses up to 1MW without quenching. Peak loss rate: about 1.65e12p/s. • This time we dumped on a TCLA collimators in RS08. • The Q8L7 reached for RS09 a factor 3.4 above the assumed quench limit. • The primary collimators experienced a temperature increase up to 10 deg.
Q6 quench test @ 450GeVPreliminary Results • Q6.L8 quenched with losses at 2500A (~4.5TeV) with 6.54E10 on the TCLIB. • No time to repeat with 7TeV equiv. current. • Energy deposition to be simulated with FLUKA and compared to QP3 prediction.
ADT fast lossesPreliminary Results • No quench when exciting 1.9e8p and 4e8p. • Q12L6 quenched with 8.2e8p lost within ~10ms. • Preliminary: factor 6-13 above quench limit.
Steady State Orbital BumpPreliminary Results • Quench of MQ.12L6.B2. • Steady losses for about 18s. • Losses in 20.9s running sum (RS12) a factor 5.5 above nominal thresholds (MF=0.1), so about 80% above expected quench level.
