H1 SEI

ETMX ISI Alignment Targets Modified

We noticed when the HEPI was untilted, some of the ISI target locations were more different than we'd like.  Mainly the Stage1 X (~70um) & RY (5urads) and Stage2 X (5um) & RY (<2urads.)  The others were less than this.  With Keita's OK we reset the ISI targets.  This will translate the tilt of HEPI more completely to the ISI (TMS) and keep the ISI stages parallel.  This may be the better place to operate the ISI rather than having the stages tilted to each other.

The attached snap shows the ISI locations with the untilted HEPI before we updated the Targets.
