(brief) Update on the target facility

M. Calviani, on behalf of the CENF SBWG teamCENF PTM meeting – 5th February 2014

Updates on integration work

Mass 35t

Upgrades on the support module design

Detail about the air tightness

A new designer (V. Clerc) will start working in the overall integration

S. Girod

Outstanding items Target cost very high

due to reduced horn inner conductor (IC) diameter (24 mm Ø) Future mechanical

studies will assume the possibility of a 30 mm IC Ø (MiniBooNE)

Preliminary neutrino studies have been performed for this config.

Cooling circuits in the cooling room

Horn & Reflector Cooling: 17-22 °C Shield + 2xHelium

cooling: 27-> °C

CV further feedbacks Hydraulic circuits under completion AL capable of executing a conceptual design of a

purification system for the CENF helium vessel1. He purity in the order of 1% can be reached with a

single membrane circuit2. He purity in the order of 0.1% can be reached with a

double cascade membrane circuit (PRESENT REFERENCE)

3. He purity in the order of the ppm (or more) requires active carbons, silica gel and cryogenic trap technology.

Radioprotection aspects Input for dump design (waste zoning) Air contamination for the He vessel (1%, 0.1%

and ppm)

C. Strabel

Dump (1st and 2nd) installation 2 solutions proposed

by EN/HE “open trench” solution Installation with blocks

on baskets After an ensuing

discussions a hybrid solution with the first dump installed via a vertical shaft will be further investigated
