## Revision as of 08:52, 14 July 2021

### Overview of Configurations (June 2021)

- Location: IP6, IP8

- Configuration: 1.5T (ECCE), 2.0T (CORE), 3T (ATHENA)

- Location of EEEMCAL: inside or outside DIRC

### Location and number of radiator modules

**ATHENA:**

- z = 195cm
- R_in = 11 cm (eta ~ -3.5) = R_min_PWO
- R_max_PWO = 53cm (eta ~2) = R_min_Glass
- R_max_total = 100 cm (eta ~ 1.4) = R_max_Glass

- Modules PWO = ~ 2200 (2 x 2 x 20 cm3)
- Modules Glass = ~ 1400 (4 x 4 x 40 cm3)

- Total weight: ~ 2400 kg

- If assume all PWO for this volume: 7600 PWO modules

- Weight ~ 7000 kg

**ECCE:**

- z = 190 cm
- R_min = 11cm (eta ~3.5) = R_min_PWO
- R_max_PWO = 49cm (eta ~2) = R_min_Glass
- R_max_total = 57 cm (eta ~1.9) = R_max_Glass

- Modules PWO = 1680 (2 x 2 x 20 cm3)
- Modules Glass = 160 (4 x 4 x 40 cm3)

- Total weight: ~1500 kg

- If assume all PWO for this volume: 2960 PWO modules

- Total weight ~ 2000kg

**CORE**

- z = 110cm
- R_min=8.5cm
- R_max=47cm

- Modules PWO = 1412 (2 x 2 x 20 cm3)

- Total weight ~ 1000kg

### Mechanical aspects

- Maintenance

- Detector maintenance will be done outside the hall using the mechanism illustrated in these videos:

- How many parts of the detector?

- One part EEEMCal (Athena and ECCE)

- Must we take out the detector?

- All major maintenance will be performed outside the hall

- Where will the detector be mounted?

- On the universal ("DIRC") frame for both Athena and ECCE

- What is keeping the crystals/glass blocks in place?

- Carbon structure between crystals (individual or matrix) - need to know what minimum thickness is required mechanically.

- Where is the detector located?

- Inside DIRC for both Athena and ECCE
- Detector location in z: z=195cm (Athena), z=190cm (ECCE)
- Detector dimensions:

- Athena: Rmin=15cm, Rmax=100cm
- ECCE: Rmin=11cm, Rmax=57cm (support radius=61cm)

- Cooling:

- Need to have as much active area (crystal/glass) as possible to minimize gaps in physics coverage
- Prefer a cooling solution from back and "inside" to minimize any structure outside the crystal/glass block outer radius
