Minutes of DRAGON meeting 17th February 2004.

Present: Cybele Jewett (CJ), Art Olin (AO), Mike Lamey (ML), John D'Auria
(JDA), Lothar Buchmann (LB), Dave Hutcheon (DH), Goertz Ruprecht (GR),
Dave Ottewell (DO), Josh Slater (JS), Jonty Pearson (JP) - recorder.

1. Corrections to Previous Minutes:
Minutes of 10th Feb were accepted without change.

2. Lake Louise Conference:
ML received second prize for presentation on MCP detector. All other
presentations went well.

3. Facility Status:
DO - New turbo pump appears to be working well; ran overnight and held
vacuum. 
LB suggests vacuum tests before running begins. EPICS still needs pump
adding.
ML - ED1 is at 180 kV, ED2 is at 145.5 kV and tripped over the
weekend.

4. JDA - What is the status of the DSSSD detector, do we need anymore
DSSSDs and is it necessary to order more detectors for the forthcoming runs?
Heinz currently has 1 detector and there is also 1 in a cupboard. It is
suggested that ML puts a list of DSSSD detectors onto the web. 
Also regarding detectors, do we need the back-end EPICS pages updating
for the MCP detector? And ML suggests adding a needle valve to the 
current vacuum set-up under the slip box.

5. JS - GEANT 12C + 12C simulations are now working. The target, pumping
tubes and histograms have been changed. See attachments. Issue raised by
JDA about how can it is possible to check the simulations to see if they
are giving reasonable results.

6. LB - Presents latest results from 12C(a,g)16O data for the 6.05 MeV
state. Plot of S-factor shown - see attachments. AO queries whether LB's
calibration is correct as there appear to be more low energy counts in
each peak.

7. Plans for detector tests: 
ML - Presents run plan for upcoming tests of MCP energy and timing. See
attachment. Discussion over which choice of beam to use and which
reaction, 13C(p,g)14N or 21Ne(p,g)22Na? 
AO - Plans for tests with Catania detector. Aim is to measure energy
resolution and thickness variations of DE detector. Again, discussion
over which beam to use. AO prefers 21Ne as energy loss is greater but could
use 13C. AO also requests singles and 2d EDE spectra in online sort.

8. JDA - Contributions to upcoming conferences: 
NIC - LB, ML , Others ????
CAP - LB, AO 
ENAM - JDA

9. JDA - Announces meeting for all parties interested in 11C (as the
methane molecule CH4) beam production via an alternative method using 
13 MeV protons at TR13. Meeting to take place in the Board Room on 
Thursday 19th February.
