Minutes of DRAGON meeting Tues Oct 24, 11am Auditorium PM, DH, CR, JP, JDA, CV, LB, MMP(recorder) Hardware -------- * JD- why is vacuum in ED2 at 10^-7 ? (usually 10^-8) > DH said it was "fine", only the ion pump is on. * PM - working on better feedthrough than swagelock for DSSSD cooling. * JD - what about the ion gauge on the Mass slit box ? > PM trying to get it replaced under warranty. have 3 or 4 months left. * PM - ED2 SF6 has been topped up. alpha measurements ------------------- * JP - source was too too low relative to the beam pipe when mounted on solid target > fixed. ISAC beam ---------- * DH - RFQ and DTL checked out, ISAC-2 accelerator being "validated" > waiting for signatures to start operator training (2-3 weeks) --> _possible_ to get some 20Ne beam next week for a few days to do (p,gamma) remeasurement. > JP says that it will take a couple of days to get things ready NSERC site visit ---------------- * DH will summarize work, and then CR and CV will talk about their work. * DH - reminder (Wed Oct 25) at 10:10 GSC wants to meet with RAs EEC Proposal suggestions ------------------------ * deadline- OCT 27 * 33S proposal ready since August (Anuj Parukh) > requires ECR on OLIS to get 2+ beam . Keerthi says it is possible. > potential collaborators should contact Anuj. * 25Mg(p,g) - CV says first draft is written > animated discussion about mechanism to separate 26gAl-26mAl products * 11C(p,g) - proposal is being reworked to focus on an important resonance > request is down to 20 shifts from 60 > 11B(p,g) may be a problem if too much 11B in the beam > some discussion about "unchanged" nature of proposal > LB points out that priority proportional to astrophysical importance, not difficulty * 18F - received update from Alison Laird > LB points out possibility of 18O isobaric contaminent > CR reports that level scheme being worked on > JDA: CR and Alison will be in York, so should JP present ? will avoid videoconferencing issues. Other Business -------------- * LB - 12C(a,g) Letter has been re-resubmitted. meeting adjourned 11:45
