Transport items Detailed assessment of

requirements with HE ongoing 40 ton crane

Redundant, but at which level? Issue when hot object are removed

form the trench to move into the morgue

Ideas of modify the support structure (*) to allow for a “flask/bell”-like configuration factor of ~50x attenuation with 4 cm Pb

+ 2 cm Fe (1 Sv/h 20 mSv/h) … but ~25 ton shielding

5 ton crane for “small” manipulation

6 June 2013

Possible need for a “crane” to move material inside the cooling station rooms (manual?) ~2 ton (CV input!)

Target brainstorming

6 June 2013

Target design/brainstorming ongoing to try to solve the issue of target bending Design with a max acceptable sagitta of 1 mm,

with 3 mm clearance between external target container and inner conductor

One idea is to have Be stiffeners to sustain the weight of the graphite max thickness of the Ti-body shall be ~0.5 mm

9 M. Calviani - CENF PTM

VSC sector valves principle

6 June 2013

First ideas with TE/VSC for the sectorization of the primary line

Further discussions needed for the primary/secondary beam interface

Comments

1. Reduction of upstream shielding will be considered

1.6 m pure Fe2. Investigate the possibility to reduce the

aperture Depends on the design of the primary beam line

and the effect of losing an MB Installation of a passive “mask” should be

considered DGS/SEE will perform a thorough analysis of

the ventilation/extraction requirements with the RP input He-vessel flush every shutdown 3H release Ventilation requirements underground area

Follow-up

EN/CV = requirements, loads, space, accessibility, etc.

EN/EL = configuration/requirements as soon as loads are ready Max 50 m between switchgear and HV transformer

DGS/RP/RW = possible reuse of CERN waste GS/ASE = first discussions on access system

requirements TE/VSC (TBC) = primary/secondary beam

interface and He pumping PH/DT (TBC) = Horn/reflector electrical

configuration CNGS experience 6 June 2013
