Proposed layout of the CRT Top Unit

The top unit of the tagger will be placed in the volume immediately below the concrete shielding plug. The largest space to be covered under the concrete plug is 27.1 11.2 m2. The allowed vertical space is about 30 cm. A set of IPE140 beams will span across the 11.2 m of lateral opening of the pit. In total 28 beams will cover the entire surface with a distance of about 1 m adjustable. Two beams support 6 modules therefore ~1 ton of weight is distributed over the opening. The inclined modules located in the left, right and back side will be brought down by help of crane and put on the moveable structure as shown below. Then the structure will be inclined to its final location and lock with help of steel rope. The modules in the front side will be supported by two 11.2 m long IPE140 beams (the structure shown in red in Figure).

The idea is to install independent square modules placed each one contiguous to the next one. Each module contains both X and Y oriented scintillator bars. the entire surface below the concrete plug will be covered by 84 modules of dimension 1.86 1.86 m2, leaving a minimal space on the sides for services. Additional 38 modules will be inclined at about 30 degreed to assemble the sloping parts of the top CRT unit. Including 3% of spare modules, we will need about 125 modules in total. The non active area between contiguous modules will be kept minimal and below 1% of the entire surface. Each module is equipped with its own light readout system and the front-end electronics. The connectivity requirements are kept minimal.

CRT module design

First Design:

Each module will be placed inside an Al box of external dimension of 186186 cm2 . Aluminium U-profile 1 mm thick will close laterally the box and reinforced by adding 3 pieces of U-profile below. The top aluminium plate will be 0.5 mm thick, the lower one 2 mm and will support the box on the rail system,
