TANB Integration – LS2 BLM Relocation Proposal C4R8 and C4L8 M. Gonzalez de la Aleja, P. Santos Diaz 18/09/2017

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. 170mm IP8 Ion pump BPM y BLM really close to the new BPM position for LS2 layout x

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 TCTPV BPM alignment IP8 Ion pump ≈ 515 mm BPM alignment BPM y x

LS2 - TANB area - C4R8 BLM relocation proposal for R8 LS2 layout TCTPV *According to 3D model for R8, distance between BLM axis and Beam axis: 190mm Proposal LS2 layout ≈ 150mm Present BLM* Min. distance needed: 100 mm Proposal: Move BLM: - about 150mm towards the TCTPH (y) Bake-out jacket (20mm thickness) TCTPV 190mm IP8 BPM Ion pump y x

LS2 - TANB area - C4R8 BLM relocation proposal for R8 LS2 layout TCTPV Bake-out jacket (20mm thickness) Access for baking-out ≈ 285mm TCTPV IP8 BPM ≈ 300mm Ion pump BPM alignment New BPM support y x
