PPRP Feedback
• Despite frequent requests for feedback, no
official response until Science Committee met on
31st Jan 07.
• We had submitted a letter to SC re-emphasizing
the quality of our work and the need for a 3-year
programme.
• We were given one year “bridging” funds of £3M.
• We were also asked to produce a 3-year
programme at approximately £3M p.a., which is
also in line with the PPRP priorities; details will be
provided by the WP managers later.
PPRP Scenarios
Visiting
Panel
• Optimal: represents the best use of
resources to maximise return, ~ 70% of
original cost
• Cut A: represents potential loss of
leadership, ~50% of original cost.
• Cut B: represents a strategic retreat from
the current successful position ~40% of
original proposed costs – aim to continue to
do some areas properly and pull out of others
completely.
I am still waiting for a detailed agenda from PPARC
The situation
is
made
harder
by:
SUMMARY
• The revised agreement between PPARC and CCLRC
whereby there will be no explicit contribution from
CCLRC to the ILC. Currently the CCLRC contribution
is approximately £0.5M p.a.
• Erosion of the cash value by Full Economic Costing.
For example, the cost of a university RA has
increased in some cases from around £50k p.a. to
£70k p.a. (both in 2006 £).
• Erosion of the cash value by inflation.
• The cessation of the accelerator studentships
programme; any project studentships will now have
to be supported from the project award.
• The completion of the EuroTeV programme. EuroTeV
funds had been used to bolster the PPARC/CCLRC
resource for LC-ABD phase 1
The Phase 2 SUMMARY
WP managers came up with
2 scenarios:
All in £k
2007/8 2008/9 2009/10 Total by WP
Scenario 1 3000.0 3316.8 3064.1
9380.9
Scenario 2 3000.0 4827.5
4553.2
12380.7
• Scenario 1 is likely to be (broadly) funded.
• The fine details of Scenario 1 are being worked out.
• Scenario 2 is an aspiration, as input to the STFC
Accelerator science review, due for this year. It represents,
approximately, the PPRP “cut A” scenario plus some delay.
Current
Status
SUMMARY
• A programme has been worked out under 2
scenarios (see above)
• The detailed programmes have been worked
out by WP managers/task leaders.
• Some optimisation is being addressed within
the Accelerator Institutes with respect to their
internal programmes.
• Some fine tuning with respect to the detailed
funding profile (new posts, key hardware etc.)
is ongoing.
• Phase 2 should have started April 1st 2007…
