Minutes of DRAGON meeting, August 31st, 2004.
------------------------------------------

Present: DH, DO, AO, JP, JC, CJ, KO, GR (recorder)


1. Correction to previous minutes
---------------------------------

DH has a list of corrections. KO will put the corrected version on the minutes 
web page.

2. Status/progress reports
--------------------------

	- DAQ

- JP was almost busy with his crashed laptop hard disk and the installation of 
the new disk.
- Found a bug in his DAQ code. Receives TDC header without following data.
- Another bug: If the heavy ion rate exceeds the gamma rate the system will be 
locked which looks as the system is crashed.

	- Magnet P/S

- C. Reineger still on vacation till Sept. 9th.

	- YSLITM
- JC checked the FC and slits. Still not sure, but there it seems that the 
drive has a too much play. However, it's ready for pump down.

	- ED1
- JC ordered the new boards. They can't find 110 Ohm carbon resistors (only 
120).

	- PGAC
- JC was playing around with the anode resistors to see why the signals of the 
fission fragments are clipping too early. Unfortunately they didn't change.
- Wants to order a 252Cf source (500 $). Are there sources available?
- JP: We must ask Pat Walden for The TUDA triple alpha source. It's not usable 
for DRAGON - the three lines are too close.
- DH/AO discussing about other groups that are interested in a source as well.

	- IC gas system
- DO presents a hand drawing (see attachment) and explains details of the GHS. 
The leftmost part is not working yet but the right side seems to work.
- What happens in the case of an explosive event?
DH got email from Cam Marshall: The damage depends strongly on the kind of 
the "bang". It is hard to tell what happens. Depends on e.g. whether parts 
are shot around.
- In order to avoid sparkling wires in isobutane Robert Openshaw will try 
to set up a high voltage interlock.

	- Catania Detector
- AO: The problem of multiple lines is obviously a cooling problem of the 
preamp boards.

- What can be used for cooling? Ethylene-Glycol as for TUDA?

3. New business
---------------

	- fall/winter beam schedule  (DH)
- September is for E991
- DRAGON has the first October week.
- Then 2 weeks for Li people and 1 week for the Lovaine people
- Perhaps last October week available

	- CCD meets EM1/FC4/FCM2  (KO)
KO gives a report (see attachment) how far the beam current can be derived 
from the CCD.
CCD values can only be compared with same exposure times. However, it is hard 
to see a correlation of CCD and EM0 or FCM2 for the last 12C(a,g) run.
