Subject: Linac4->Linac2 reversion options
Hello Maurizio,
If we take the double line PFN option then reverting to Linac2 configuration
would take a maximum of three weeks.
If this option is not taken then we would be required to re-install the original
BI.DIS PFNs at a time cost of two months. There is a complication in that this
equipment is in need of consolidation to the cost of 600kCHF which would only
begin once the decision to revert had been taken. Hence the 'old' PFN would be
re-installed and then long-lead consolidation components would be ordered for
installation at the next shutdown opportunity.
Cheers,
Tony

Maurizio,
Our Linac4 to linac2 backwards compatibility costing is as follows:
BISMV: 0.2 FTE + 12.5kchf (plus requirement that the new power supply can deal
with both the old and new device)
BISMH: 0.3 FTE + 12.5kchf (after injection area is liberated, plus requirement
that the old power supply needs to be set-up somewhere else and connected)
BI.BS Removal and BI.KSW Re-installation: 0.4 FTE + 30 kchf
BIDIS-magnet: backwards compatible.
BI.DIS-Powering: 0.4 FTE + 60kchf

Dear Maurizio,
Please find below a resume of our cost estimates.
Cost estimates [kchf]
2007 2008 2009 2010 2011 Total
BT-TL 60 176
162 88

BT-SE 200 750 700

7820
Total 360 1926
4112 3738 220 10356
This does not include a two line parallel PFN which will allow easy Linac2
reversion to 25ohms at an additional cost of 300kCHF. If this option is not
taken then an additional 600kCHF and two months intervention will be required
for re-establishing the PFNs for Linac2 injection.
Greetings, Wim
