EMR Design & Module M0 prototype

As a recall…

KL

EMR

  • EMR features:

  • 24 modules

  • 1 module is made of X&Y planes

  • Nearly 11 km of WLS fibers

  • (1.2mm diam.)

  • 48 multianode PMT

  • 48 single pixel PMT

  • 28 Kg per plane (1,4 Ton totally)

Module M0 prototype

  • 2 planes X & Y have been assembled

    in a wooden black box…

  • a good experience to get a better feeling

  • about final schedule …

EMR Production status

Nicolas & Laurent

STEP 1:

Bar cutting to length almost completed!

(from 3.5mm to 1.1m)

EMR Production status

STEP 2:

Fine milling of the bars (1100 +/-0.1mm)…on going at MECATEST in Geneva (sub contrator).

2 batches remaining (due date: first week of February).

This includes: milling, drilling (for glue injection) and tapping (for insert fixation)

EMR Production status (tentative schedule)

  • The full production of fiber gluing will start soon (within a week or so).

  • The pace will be 20 complete gluing per day (already challenging!!)

  • That means:

  • 1 plane per week (or 2 modules per month)

  • 2 modules to be tested per month … looks feasible (manpower is not sufficient to speed it up)

  • Based on the 1rst Module 0, it’s achievable but without any margin!

STEP 3: Gluing and fiber insertion (all the inserts in aluminum are ready for assembly)…

right after the white painting of the bar ends (done in one go)

EMR simulations (FEA studies)

  • Ongoing, are 2 different studies:

  • One from Ghislain Gregoire on Magnetic shielding (by OPERA),

  • One from F.Cadoux about mechanical behaviour (sagging, stresses…

  • in order to size the EMR Outer Box properly.

FEA model of the whole EMR

3D IGES model of

the all shielding

Meshing without covering plates

EMR simulations (FEA studies)

  • Sagging and stresses look OK (60x60mmx3mm cross section beams).

  • It showed the need of reinforcing the 4 corners (connections between modules)

  • by means of aluminum corner beams.

  • Several configurations studied:

  • Transportion loads (horizontal)

  • Rotation to get it upright @ RAL

  • - 1G Loading when vertical (in situ)

Worst case study:

No side panels,

No end plates (Top and bottom)

Slings for

Handling

(used for

rotation)

Building/platform issues (anticipation / differents STEPS of MICE)

EMR Box

The EMR Outer Box will comply with the differents STEPS (moving downstream)

So, we have to work closely with Tim, Andy,… to make sure that no interference with platform

occurs…anytime! CAD works first and soon (to freeze the Outer Box)
