2010 Schedule The 2010 Accelerator Schedule v. 1.3, as
approved by the RB on 2 December, was used as basis taking into account: The start and end dates of each
facility/experiment. That the LHC monthly technical stops that are
taken as MD and technical stops, thus no physics
Five dedicated and floating 8 hour MD’s that are put on the schedule as place holder, but that might shift in time.

Changes following recent SPSC meeting(19 – 20 January 2010)
The SPSC anticipated shortfalls and has made proposals to reduce the impact on certain experiments/facilities
CNGS earlier start (2 weeks) 29 April instead of 12 May
1 EASTB cycle less to give 1 nTOF cycle more resulting in: 4 EASTB cycles day and night 4 dedicated nTOF cycles day and night

Machine/Facility Limitations Maximum beam current of 2 µA for ISOLDE Maximum PS MPS load until POPS is operational
Based on 1.16x108 MJoules per year/run RMS current SMH57
Less cycles required if beam sharing reintroduced. As long as there are enough CNGS cycles
following the (long) FT cycle there is no rms issue on the SPS MPS
PSB and PS are surface machines beam losses generate certain radiation levels outside the machine
Every change in the SPS super cycle has knock-on consequences for the PSB and PS users

PS MPS Load calculation 30 weeks of PS
running, not counting running for LHC alone
5040 hours Slightly lower than
2009 run time Therefore the
average 5 MW limit for PS MPS remains valid
Not taking into account the periods of dedicated LHC running

Proposed basic 2010 super cycles There are four basic super cycles
proposed: Operational day super cycle containing:
SPS: Fixed target, CNGS, LHC or MD PSB/PS: nTOF, AD, East Area, ISOLDE, MD
Operational night super cycle containing: SPS: Fixed target, CNGS PSB/PS: nTOF, AD, East Area, ISOLDE, MD
LHC filling super cycle for protons LHC filling super cycle for ions

Basic assumptions Day super cycles from 08:00 until 18:00 10 hours
Night super cycle from 18:00 until 08:00 14 hours
Dedicated LHC filling (protons & ions) will take on average 4 hours per 24 hours, leaving 20 hours per day for other physics.
No Physics during MD’s 5 x 3 days = 15 days 360 hours 5 x 8 hours = 40 hours
Ion commissioning foreseen on MD cycle Last years’ machine availabilities are taken into

The other physics beams displayed are not taken into account for the intensity/spill planning
ISOLDE (HRS & GPS & REX) 2010 running Starts 26 April, finishes 22 November giving 210
days Taking into account the MD’s etc. this leaves 210 –
15 - 2 = 193 days for physics (556 8-hour shifts) ISOLDE bases their schedule on 8-hour shifts with 2
µA on target To have 2 µA on target they need 43% duty cycle
with 3x1013 protons per cycle In the proposed super cycles ISOLDE will have:
36% duty cycle during day-time (excl. LHC filling time) 33% duty cycle during night-time (excl. LHC filling time)
Final ISOLDE physics schedule available in March

DIRAC request and particularities
Initially approved for 2.1x106 spills per year The intensity per spill is 1.1x1011 protons
Produced using 4 PSB rings very low intensity DIRAC cannot accept parasitic nTOF beam
DIRAC – nTOF bunch intensity not compatible for single beam control
Spill quality degrades too much (peaks/spikes) SPSC in January proposed to give 1 cycle
less to DIRAC with respect to 2009 and give it to nTOF instead. (remains to be approved by RB)

Starts 29 April, finishes 22 November giving 209 days
Taking into account the MD’s etc. this leaves 209 – 15 - 2 = 192 days for physics
To provide 2.1x106 spills we would need 35% of the super cycle for DIRAC (EASTB)
In the proposed super cycles DIRAC will have 4 EASTB cycle per super cycle day and night (~ 21% duty cycle)

Dedicated single bunch: 7x1012 protons Parasitic single bunch: 3.5x1012 protons
Just before extraction there is a bunch rotation to shorten the bunch to below 25 ns (4σ).
The nTOF facility can practically receive 4.9x1019 p.o.t. per year Improved cooling, ventilation and shielding
At start-up 2010 the experimental zone will be a “Class A Laboratory”

Recently SPSC proposed moving the CNGS start forwards by two weeks (approval RB ?)
Starts 28 April, finishes 22 November giving 207 days
Taking into account the MD’s etc. this leaves 207 – 15 - 2 = 190 days for physics
Access to CNGS beam area requires often slightly longer stops than the 3 day MD period.

3.75x1019 protons foreseen for 2010
83% of required intensity
Without 2 week extension we will achieve 3.4x1019 protons integrated for 2010.
SPS North Area (COMPASS)
Starts 10 May, finishes 22 November giving 196 days
Taking into account the MD’s etc. this leaves 196 – 15 - 2 = 179 days for physics
3x105 spills of 9.6 sec requested User time nearly fully scheduled

Possible means to reduce short falls (1) ISOLDE:
Pulse PSB at 600 ms, while keeping PS with same bp length > 50% guaranteed duty cycle for ISOLDE Every 2nd cycle for PS if required (more than at present)
Can we use synergy for LHC upgrade proposal ? Higher primary beam energy fewer protons required ?
East Area: Large number of East Area cycles required in super cycle Re-instate beam sharing to avoid cycle duplication Cycle requirements in new East Area lay-out proposal ? (see
talk Lau Gatignon) Future of DIRAC in PS ? (plans to move to SPS after 2011) More effective use of EASTB cycles for DIRAC
Higher intensity with less cycles gives same integrated intensity ? Would make parasitic nTOF perhaps possible

Possible means to reduce short falls (2) nTOF:
Try to produce higher intensity for dedicated nTOF cycle (8x1012 instead of 7x1012 + 14%)
Fission experiments could accept multiple bunches with specific spacing to be checked
In general: Prolong run for PS complex into reduced
power consumption period (PS complex cycling is not so expensive)
Evaluate possibilities to optimise cycles following POPS commissioning in PS

Conclusions The requests for certain facilities exceed by
large the production means A set of reasonably achievable goals for 2010
are proposed. For the longer term we will have to improve the
production capability and try to use our facilities more efficiently if we have to meet the requests
Some possible fields of improvement: 600 ms pulsing of PSB guaranteed 50% ISOLDE duty
cycle Reintroduce East Area beam sharing to minimize cycle
duplication (depends on approval of newly proposed lay-out)
Increase dedicated nTOF bunch intensity to 8x1012
Profit from possible synergy with LHC upgrade proposal
