  1. - assembly is proceeding to check possible mechanical flaws • Small tilt along z (~2 mm): being investigated, maybe poor quality of the bearing ?

  2. 2) Some elements showed magnetic properties • These were notice with a small rare earths • Magnet • The effect is tiny but not easy to quantify • Nonetheless some calculationshave been • done by hane (John) and FEA (Holger Witte) • Using B-H curves from literature • It seems that we have: • 2 kgf on the gear wheel • 25 kgf on the drum • BUT we need to assess the real • B-H for the material used • SS316 seems much less magnetic than SS304 after stress relief • We are sending two samples (SS304/316) to a lab in Dresden to check mu_r/B-H • After which a complete FEA should give us the answer. • Probably remachine some parts in SS316 This turned out to be all SS304 parts which underwent a heat treatment (stress relieved or welded). SS304 is “non magnetic” steel which can assume magnetic properties due to heat (welding) 10 kgf 2 kgf

  3. Air system in progress (P. Lau)  contacted Tim Hayler for space/air quality • requirements in the MICE Hall • Electronics: in progress (M. Dawson, CEG) • Aiming at end of August: • Complete mechanical • Complete electronics • Merge a)+b) • Urge a quench test in the solenoid without tracker
