Subject: JEM-X Monday Meeting 2006-10-12
Date: Thu, 12 Oct 2006 15:24:03 +0200 (MEST)

Participants: CAO, NL, ILR, CBJ, JC, SB, AH, NJW.

JEM-X status (SB): Works nominally. The exercise with a single anode segment
active was performed during the Crab calibration. It demonstrates that
it is possible to operate in this mode including sky image generation.
It could be used in the situation where the JEM-X instrument is shut down
because of too high trigger rates. The usefulness is still somewhat uncertain.
Inside a ScW of 2.5 ks. IJD = 2463.06

Gain correction for JMX2 during Crab calibration worked fine except for a
single value that stands out; probably due to old start up HV procedure.

OSA 6 status (NL, NJW): SP has highlighted the source contamination problem.
The extraction of Crab spectra works differently between OSA5.1 and OSA6
which is a surprise, since nothing has changed (presumably).

Report from IUG and ISWT meetings (NL): Review of the management of the
science program. Too few projects exist and they are too expensive.
Call for new missions due spring 2007 has been postponed. 200 Meuro are
missing and INTEGRAL+XMM cost 25 Meuro per year.
Spectral extraction problems both in JEM-X and ISGRI are still serious.
A unique Crab reference spectrum is missing (needs not be the correct
one).
We will have to make a very convincing presentation of how well INTEGRAL
works and how accurate the results are for the next review of INTEGRAL
prolongation - probably around mid 2007.
After 2009 there will be no core program.

When the end-of-mission time is known it will be reasonable to operate
with both JEM-Xs - and there seems to be enough TM packets to do this.

The correction for temperature effects can now be routinely obtained
from the OMC pointing relative to the startrackers.

Next INTEGRAL workshop in Denmark in 2008, probably September.
Should we define a theme in order to focus the
meeting plus session topics? Necessary with e.g. review talks that covers
all subjects of interest to INTEGRAL?

We need to define a local organizing committee.
