DRAGON GROUP MEETING MINUTES   19 Oct 04


Present   JDA DH DO(recorder) MT LB GR CV AO DG CJ


Move to total VME system 
 
      Renee is supportive of this proposal, and is willing to commit to 
normal TRIUMF support of manpower and hardware.  JMP is also aware of the 
proposal although we ensure he is familiar with some of the details. Some 
discussion of analog BGO signals and sampling, instead of new ADCs.

DAQ  A.O. 

       Funny triggers are gone, however now EPICS gives occasional errors.
DAQ is needed in 9 days.

Ion Chamber Review
  
       Safety review of chamber and new plc controls to be held 20 Oct 04.

GEANT Simulation  MT DG

       Gamma ray simulation and total DRAGON simulations are now separate 
but will be combined.  This may take 1 week debugging.

Priorities to EEC   JDA

        Some discussion of priorities.  DH has been asked by JMP to provide 
list of technical feasibilities independent of science priorities.  Two lists 
were presented by JDA and discussion ensued.  
22Na(p,gamma) to be done in Seattle was removed from list as a non DRAGON expt.
12C(alpha,gamma) was moved to bottom of list as an easy beam but needing 
significant modifications to the front end of DRAGON.  Lists attached are 
attached but a new list will be presented next week.

DSSSD stuff  CV 
 
         Analysis of 1 strip shows energy resolution still not sufficient 
to separate leaky beam.
         New DSSSD with thin dead layer in strips costs 7000 Euros¡Ä.

Practice talk to DNP of the APS presented by  CJ 

 A session will be scheduled to allow CJ to practice a 30 minute interview 
talk.
          

Priorities for DRAGON: Submission to EEC (Dec. 2004)

Science Priority (Radioactive Beams)
E813 15O(a,g)19Ne  	needs a short rationale paragraph to accompany 
submission

E922 25Al(p,g)26Si   	Alan Chen will resubmit one page summary

E989 26gAl(p,g)27Si	Active and does not need submission, but report 
could be useful (CR)

E989 26mAl(p,g)27Si     Needs TUDA experiment initially, but could be 
included above by CR

E811 19Ne(p,g)20Na    Uwe Greife will resubmit a one page summary

22Na(p,g)23Mg             Due to new data, needs remeasurement; to be 
submitted to EEC; Seattle exp.

E946 17F(p,g)18Ne	Important for hot CNO; will be resubmitted when beam 
possible.

E810 23Mg(p,g)24Al    Important for NeNa breakout to rp; will be 
submitted when beam possible

E905 13N(p,g)14O     	Direct capture needs measurement; JDK suggests no 
submission now. 

E983 11C(p,g)12N	Does not need to be presented now; beam not available 
yet.

Science Priority List (Stable Beams)

E952 12C(a,g)14O 	Considered highest priority in astrophysics; needs 
report (LB)

40Ca(a,g)44Ti		To be subm. to EEC (CV); important for 44Ti prod. in 
universe


Feasibility Priority List (Heavy ion  Beams) 

E989 26gAl(p,g)27Si	Active and does not need submission, but report 
could be useful (CR)

E989 26mAl(p,g)27Si     Could get enough for TUDA studies; SiC slow 
target, needs new tgt.

E922 25Al(p,g)26Si   	Need to test laser source yield with SiC, then 
new target.

E811 19Ne(p,g)20Na     FEBIAD or new ECR could get sufficient beam 
intensity

40Ca(a,g)44Ti		Needs some initial testing and 2+ beam from OLIS.

22Na(p,g)23Mg             Need beam time to make implanted target for 
Seattle or R beam??

E983 11C(p,g)12N	Depends on success of ECR/FEBIAD or E995 (Alternate 
App.)

E905 13N(p,g)14O     	Depends on success of ECR/FEBIAD or E995 
(Alternate App.)

E813 15O(a,g)19Ne  	Depends on success of ECR/FEBIAD or E995 (Alternate 
App.)

E946 17F(p,g)18Ne	Important for hot CNO; will be resubmitted when beam 
possible.

E810 23Mg(p,g)24Al    Important for NeNa breakout to rp; will be 
submitted when beam possible

E952 12C(a,g)14O	Needs serious mods to DRAGON to do properly at the low 
energies and more intense 12C beam
