9. Our Approach to Java Applications Development
A considerable amount of applications for stage I & II is requested
This will be achieved since we have put in place a common architecture based on
a solid core functionality
a standard equipment access
reusable software components
standard facilities
upon which the LHC applications are being built
This requires high competence in software engineering for core development BUT it pays back
Complex self contained applications are replaced by light weight GUI applications which are easier to develop
GUI applications based on the core are less error prone

The work is done in a close collaboration with the OP group - we work in a team
One single project in place (LSA *) providing the common architecture
Aim to use for several accelerators TT40, TI8, HWC, LEIR, SPS, sector test and LHC
Test using every possible controls or operational milestone and several dry runs
* In 2006: 4 CO FTE and ~5 OP FTE

Application PVSS is operationnal for the moment for QRL. It is the same application for all 4 vacuum ( 2 beams, 1 magnet and 1 QRL vacuum). Connection to Laser and logging forseen via PVSS.
All the 4 vacuum will be controled by the same application: PVSS application, already in used for QRL. With this application, Pressure data are logged in LHC logging database and alarms send to Laser system. The position of sector valves will be seen in PVSS ( like it is for SPS or LEIR). We didn't log state of sector valve for the moment but we are working on it.

Issues - Resources
The system architect & core developer leaves CERN in May
Major core activities are staffed by temp or departing staff
The same application developers are working for HWC, LEIR, CNGS, PS and SPS startup and …..
what is left of them … for LHC Beam Operations…
LHC applications list not fully staffed clearly showing lack of resources
We need experienced Java software developers

25. Issues -Time allocated for Testing
While TT40/TI8, HWC, LEIR, and SPS ring will be used to test the LSA core and applications extensively, …
the tests foreseen in 2006
CNGS
TI8/TT40
sector test
will be the only validation of the LHC software, so …
we need well coordinated dry runs beforehand
We request time allocated during LHC commissioning for the final tests of the deployed software

Chamonix XV: Commitments and Major Issues on LHC Applications

26. Issues - Remote Access and Security
Experts and piquet require access to LHC controls from outside the CCC
Who has the right to modify LHC parameters?
Control of certain devices (Schottky) from other institutes is already requested (US-LARP collaboration)
We need remote access and role based access policy and manpower to implement it
CNIC is not the answer
Remote replication of LHC databases (logging, measurements) at FNAL
proposed as well.
