7. On-site visitors should make travel arrangements.

8. Register and Ship your crystals (Failure to follow instructions will results in delivery refusal at APS):

a) Please complete a  puck registration form. Please make arrangements early and have the form           submitted  by 5PM on the day before Harvard's data collection starts.

b) All dewars and corresponding shippers for the CMCD trips should have a clear, big label in the following format: HU-PI's Initials-dewar number, e.g. HU-SCH-1, HU-SCH-2, HU-SCH-3 for Harrison lab or HU-PS-1 for Sliz group.

c) With many labs traveling please try to consolidate shipping - saves money and effort on the APS end. Please note that number of pucks indicated on the schedule represent the maximum number that will be loaded for your group. You can certainly have fewer pucks.

d) The final ** packing list for each dewar must be included** in each shipper. If there are last minute scratches just indicate this on your packing list. There is no need to email coordinators with this info.

e) U sers should include a return FEDEX label inside the case when they ship. Express saver works best in most cases.

GO-TO-Chicago (GTC) Points

Each trip will be attended on-site by one CMCD laboratory (at least one person on-site for the duration of 48 hour CMCD data collection slot).

The lab with the highest number of GTC points will be required to provide this support. GTC points are collected based on number of previous NE-CAT shifts (0.5 points per hour of data collection on E and 0.75 points per hour of data collection on C).
