Pre-CM33 schedule planningSuperMICO meeting, June 6th

Motivation:

For all of us to understand the main drivers behind the top-level MICE schedule

So that there are no surprises at the Collaboration meeting

So that we can give a coherent story to the MPB, UK OsC and the FAC

Useful meeting, good participation, thanks everybody

Main points for schedule construction follow:

spectrometer solenoids
Spectrometer solenoids

SS#1 will arrive at RAL first week of August

Will be shipped without CCRs or vacuum gear fitted

Shipping company will provide weight and C of G

Support structure (UK) due mid-July

Virostek plate mock-up making good progress, but we have to clarify expected positional accuracy, is it 1mm or 10mm? – open issue

Shipping of SS#1 & SS#2 is not desirable

Shipping mode is being considered now

Handling and lifting plans while at RAL are also being worked out

focus coil
Focus coil

Cold mass should be fitted this week

Tesla’s date for delivery is 27th June, but have agreed that we take 31st July for the MICE top-level schedule

Commissioning schedule when in R9 takes 23 days, need to check this with them

Dependent on LHe – Tesla’s responsibility to organise

Five Tesla staff attend RAL next Monday, will go through their plans with them

Mike Courthold will re-open discussion with DLS on liquid helium supply from their plant

Very aware that we need to give CERN magnet group firm dates for attendance

slide4
EMR

Good progress, delivery still planned for late October

Blondel plate due July/August

Total forces on the EMR/KL assembly are being studied – Tim needs to be in the loop – open issue

Mike & Vicky need to know the magnetic characteristics of the whole EMR/Blondel plate assembly – talk with Franck

More detailed presentations from Ruslan & Franck on MICO 190 page

magnetic field simulation
Magnetic field simulation

In light of recent revisions to the stray field simulation, we need to know where we can place racks, pumps and compressors – crucial information for Step IV schedule

We can probably have a ‘half-way house’ of Step IV compressors downstream along South wall, but shielding at some level will still be required, also shielding for racks on North mezzanine – open issue

Vicky will hope to have simulation for above in around ten days, then placement and shielding can be verified and designed/made

But for Step VI we will almost certainly have to situate most equipment behind the downstream beamstopper

diffuser
Diffuser

Diffuser assembly is complete and working

Air crate and electronics crates need rewiring and new panels

Delivery still on target

Consensus that we still need to do the quench test as part of the installation, for protection of irreplaceable tracker fibres

Tracker

Both trackers are ready for use of course, so no real schedule issues here

But we need to accurately lay out the tracker installation scenario in the Hall – open issue

beamline
Beamline

We need a plan for the decay solenoid QP and PSU upgrade installation for Step IV – Mike & Brian report to Alan G – open issue

TOF1, or a model of, can now be checked in the real TOF cage installed in R9 – Maurizio visiting this week

A fully updated target assembly will be installed for Step IV

Hydrogen system

Helium tests were complete success

Now mostly held up with internal safety and admin negotiations

Looks like we can converge on July 2ndto start R&D tests

Then 23 days of work

actions and general comments
Actions and general comments

Alan and Andy will incorporate this information in the top level schedule in time for before CM33

Important point:

When the SS is on the ship/plane and the FC is on the truck, we will be making a new schedule!

The key to planning our work is to be flexible and to bring forward activities where necessary – this has worked very well so far

The MPB has asked for a resource loaded project plan for all of MICE by October – WBS redefinition is first step, Andy will start discussions at CM
