Final machining and pre-assembly

The Kaon Aerogel detector machining is almost completed! Just a few parts are being machined, but the entire detector was already pre-assembled to check if all the parts fit together.

Some pictures of the pre-assembly of the detector are shown:

Checklist of the progress on the milling

The following checklists are an overview of the main parts of the detector and the progress on its construction. As it is going to be constructed one diffusion box and three aerogel trays, these list provide the status on the progress for each piece of all of the items.

Materials and pieces machining

The materials had been ordered by Dr. Marek. Almost all the structural pieces (aluminum pieces) was delivered on October 10th, at CUA. Paul and Michael started milling the first piece of our new detector on October 13!

The materials for the construction of the detector.

This construction is being conducting under a collaboration between the Nuclear Physics Group and the Vitreous State Laboratory group (VSL).

Ready pieces

As the machining process is going on, the first pieces of the Kaon Aerogel Detector are being ready! Paul and Michel are working at the CUA Machine Shop and the progress of the construction can be verified in the following pictures.

Pieces of the detector that are ready.

6x Tube Port Cover, to close the top ports when the optional PMTs are not being using.

2x Diffusion Box Vertical Bar, that will allow to hold the aerogel trays with the diffusion box

Interface plate and Attachment plate on the milling cutter. They are going to hold all the detector on a trail at the SHMS.

Some of the materials require the cut of large pieces, for instance, the side plates of the diffusion box and also the PMT's end plates. These cuttings are related to the pieces that will hold the PMTs in the detector. As the PMTs have an overall diameter of 5", holes with this dimensions were required in that material.

As a first step on the machining of these pieces, they were send to a company for a water cutting.

Material cutted by the water cutting, before precise machining.

All the material cutted by the water cutting machine. There are 2 side plates and one top plate of the diffusion box and also 22 PMT outer shield end plates.

One of the diffusion box vertical plate, cutted to the insertion of PMTs holding structure.

One of the PMT outer shield end plates, to hold the structure of the PMT shielding in the aerogel detector.

The following pictures show the staff working at the Machine Shop for the Kaon Aerogel Cerenkov Detector.
