The lower half of the beam dump EHDT shielding was installed yesterday by Plant Group.  After installation of the service stand plug, the position of the south and east faces of the plug were checked with the laser tracker w.r.t. EHAT MB4.  The south face was within approximately 2mm of nominal, and the east face was approximately 6mm east of nominal position.  It was decided that this positioning was acceptable.  The modified 6 foot block (TSH0387) was then installed with approximately 4mm clearance from the plug according to TSH0293.

Beamlines Group may now proceed with installation of the EHDT section of beam pipe.

Photos and results of the laser tracker measurements are attached.
