Straightness Monitor

• Cross check of spectrometer energy measurements– Commission SR-Stripe setup– Previous chicane measurements limited by BPM resolution

• LCLS2 BPMs? (under negotiation)– more new hardware/electronics for better resolution/stability– aim for 1×10-4 relative measurement, cross-calibration– Finish what we started!
