Dear all;
Here are my notes on our
meeting.
Regards.

Beam optics power supplies :
Because of the lack of OP
programmer available on short term, the migration of the interface of the beam
optics power supplies has to be postponed to November 2005. Four programs are
involving these power supplies that will need to be rewritten in Java after the
interface migration :
- A scaling program of the
REX parameters (mostly linear scaling)
- A synoptics program (to
enable physicists to easily control power supplies)
- A scanning program (VB
program involving feedback loops)
- A generic configurable
scanning program.
The first program is simple
and raises no problem; the second has already been provided to the ISOLDE
physicists and is mostly a matter of reconfigaration for the REX layout; the
third and the fouth should be merged into a single Java program for which
specifications should be readied for November. The VB code of the existing
program is thought to be a good starting poit for this specification and the
idea is to establish as soon as possible a direct contact between Thomas
/Frederik with the OP programmer that will be in charge of the new program
(J-L. Sanchez-Alvarez?). The coding work for the 3 programs (plus the generic
Working Sets and Knobs tools)should be done between November 2005 and March
2006 so that the whole new environment will be ready for the 2006 start-up.
RF equipment :
Currently there is no
high-level application programs dealing with these parameters; moreover there
will be no hardware change on the PLCs that control this equipment. The
migration of this part appears to be easily feasible and the CO effort will be
put on that as soon as possibleaiming at completion before November 2005. As a
first stage the working set / knobs should provide more functionality that the
basic tools currently used and could work in parallel with these tools reducing
the risk to a very low level. During the 2005/2006 shut down a high level
application could probably be provided by OP programmers; this application will
also be welcomed for the Rf equipment in the Linac2 and in the Linac3.
Summary :
CO will validate the
technical solution for the beam optics power supplies during the June technical
stop but wont deploy it before November when the OP manpower has been made
available for the applications and when specs (or a very good knowledge)on the
scanning program are available. For the RF equipment, CO will work on its
migration immediately after the June Technical Stop, make test on a vertical slice
and deploy the solution before November using the Working Sets/Knobs (as a 1st
stage)that should provide functionality slightly better than what exists
currently. The controls of EBIS, TRAP and the beam instrumentation will not be
not be migrated before March 2006 and the date for their migration is not yet
defined. Discussions are currently going on to extend beyond Oct.2006 the
contract of the CO person in charge of migrating the REX controls. Thomas and
Frederk will validate this approach with their REX colleagues and give us
feedback; Thomas will approach J-L Sanchez to discuss the scanning program.
Dear Bertrand and Franck
Your summary from the
meeting seems correct. Our comments are as follows:
1. We are positive to RF
programme implementation. The minor modifications necessary have been discussed
between N. Trofimov, T. Sieber and J. Marques.
2. For the application
programme specification we are willing to:
* demonstrate the programmes
* show features
* describe functionality
* show where source code is
found
* follow the programming
work and give feedback
3. We have some question
marks in connection to the time schedule. In
case a new control system
for the EBIS and Trap will not be launched next shutdown we are in strong need
of:
* development and
reprogramming of certain features in the EBIS programme such as slow ion
extraction, improved general timing, find a bug in the GFAS programme
* increased support for and
detailed knowledge of the Trap labview CS when
* maintenance and debugging
of the failing beam diagnostics FEC
Best regards
REX team
Dear Fredrik,
Thanks for your help on the
REX scanning program for OP to produce a java application for the 2006 startup.
For the trap and EBIS, we indeed have no plan yet for migrating the controls
and I believe that BDI has no plan either for the instrumentation. Concerning
extensions of the current application programs, I'm sorry to re-assess that I
have no solution in the CO group: we have neither the expertise nor the
resources to handle them.
