2. LS2 - TANB area - C4R8 BLM relocation proposal for L8 LS2 layout TCTPV
*According to 3D model for L8, distance between BLM axis and Beam axis: 170mm
Proposal
LS2 layout
Present BLM*
≈ 200mm
Min. distance needed: 30mm
Proposal:
Move BLM:
- about 200mm towards the TCT (-y)
- some mm towards the QRL (-x)
Bake-out jacket (20mm thickness)
≈ 240mm
TCTPV
Just a minimum distance of ≈ 30 mm around the ion pump must be respected.

BLM really close to the new BPM position for LS2 layout x

3. LS2 - TANB area - C4R8 BLM relocation proposal for L8 LS2 layout TCTPV
Min. distance needed: 30mm
The aim is to provide an easier access for:
- installation of bake-out jacket
- Alignment of BPM
Bake-out jacket (20mm thickness)
Access for baking-out and BPM alignment
≈ 240mm
