UA9 in LSS5….

Main questions• One MKDV tank upstream of QF518 or not?

– 2 or 3 MKDV– Dynamic range of main switches– (re)location of SSS equipment – COD, BPM.

• New functional locations needed for several items– Interlock BCTs– Instruments– Test collimators– BBLR prototypes– eCloud test systems

• Identify remaining “?” equipment• UA9

– Will it be needed after LS2?– If so, what is a possible configuration in LSS5?
