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

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.
24 + 12 mm Ø
30 + 12 mm Ø

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.

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
