5 Nov 02 Dragon Meeting Minutes:

Present: DH, AL. JR, LB, CJ, JD'A, DO, AO (recorder) + 2 TUDA people.

Business Arising from minutes: How many DSSD's do we have? There is
some confusion about whether one was received.
Facility Status: 
A connection that will allow resetting the NMR magnetometers
from the counting room is being implemented.

A digital camera will be mounted on the DRAGON beamline to facilitate tuning.

A 1.25 MeV/u Ne20 beam will be run into DRAGON on Nov 7th to do a
beam energy calibration for the upcoming TUDA run. A similar 20Na run is
expected a week later.

John D'Auria raised the possibility of a 20Na Dragon run if extra
time came our way.

Joel has tracked down the source of the intermittent noise problem
in the elastic monitors. The design of the insulator through which
the microdot is connected is marginal, leading to an insecure and
microphonics-sensitive ground. The attached figure shows the effect of
removing this insulator. The width of the pulser peak is a sensitive
indicator of this problem. The mounting will be improved ASAP!

Dragon Analysis:
A figure of our results for the 24Mg(p,gamma) reaction was
circulated. It is to be included in the 21Na letter in support of
our resonance energy value.

Joel has estimated suppression factors for (alpha, gamma) reactions
from our 14N(alpha, gamma) data. A suppression of 10-14 is found for
a 4.6T target, and it is reduced to 10-16 in the 2.2T target run. 
Imporvement of the suppression by tighter cuts is possible. A note
describing the methodology is attached.
 
A full discussion of the 21Na analysis from Shawn is expected at our
next meeting.

Alternatives proposed for the publication of the 822 keV/u resonance
were a) inclusion with the other higher 21Na resonances in a full
     paper.
     b) A separate Rapid communication.

No conclusion was reached.
