Cosmic Ray Energetics And Mass (CREAM)

Eun-Suk,

Right after I forwarded the e-mail, we had to evacuate the Willie Field due to a strong wind and ground snow blowing to the sky with a low visibility.
Now we are at the town and waiting for any further notice on the weather condition and possible return to the field.

This morning, the weather was not bad. But the wind is now getting stronger here at Willie Field. And I have attached the e-mail on the possible bad weather today.

Subject: Weather Conditions Today - Be Prepared

Greetings All,

McMurdo Weather is forecasting deteriorating weather conditions throughout today, tonight and into tomorrow. It is possible that we’ll have winds in town in the 40 knot plus range and above 50 knots out on the Ice. Visibility could drop to less than ½ mile and in some known problem areas be zero. Weather conditions could begin to change as early as noon time today. This morning, please take the time to secure loose items about town before the storm arrives and be alert to the current weather conditions. Be prepared for Weather Condition 1 announcements for the ice shelf and snow road closings. If the snow roads do close, please do not venture out on the snow roads again until they are reopened. Above all, stay safe and do not take on any risky activities. One of the greatest hazards from storms is blowing debris.

Stay Safe!

Here are what have happened today.

• Opened the wooden crate for the first priority flight back to UMD after recovery. Two PSU gray crates, calorimeter recovery trays, recovery tool box, cable protectors and CD crate were un-packed. The wooden crate was put together and moved back to the sea container "C".
• All GSE crates were moved up to the 2nd floor (mezzanine) for a storage.
• Power and Ethernet cables were secured with cable protectors taken from the wooden crate.
• TCD debugging started with Tyler's advice to check with voltages from power connectors to each concentrators. All of them were measured and +3.3 V were looked rather low according to Tyler.
• Ping to all concentrators were tried but only some of them were connected.
• From the tests results requested by Tyler as in the above, in a phone call, he suggested to push all female power connectors' pins together suspecting the same problem with a loose connection as we had in CSBF this summer. So after tightening all pins in 12 connectors, we turned on the power and the TCD came back to work. Tyler is going to think about how to improve those connectors in the future.
• Took 50 k muon events as a part of LPT. Now the LPT is complete and everything is in the same condition as we had tested at CSBF before the shipment.
• The back up PC was scanned for possible internet connection to outside. It seems quiet fast and simple. We can use DHCP for network connection unless we are going to use a static IP address. Even for the static IP address, we can apply like we did in last season for two notebook PCs.
• Chris has been preparing the SIP module. And the batteries were checked. Expect to have the SIP power tested and used tomorrow afternoon for the instrument.
• Fritz has been working on solar panels and the mezzanine organization for a storage space after the unpacking works.
• Moved to new rooms in the dorm 203C after returning to the town.

Here are things planned for tomorrow and future.

• CD HV conversion factor calibration. (Thu. AM 2 hours)
• Replace CAL spar boards and debug the noise issue. (Thu.)
• CAL trigger test. (Replace one ASIC chip which showed as dead trigger channels at CSBF before the shipping) (Thu.)
• Safe-to-mate with SIP power. (Thu.)
• TCD/CD housekeeping data long-term stability check. (Thu. - Sat.)
• CPT (Fri.-Sat.)
• Connection test with SOC. (Sat.)
• Takes photos for the recovery plan manual update. (Wed. - Sat.)

Please let me know if you  have any questions/comments.

Eun-Suk,

We have arrived at McMurdo station safely after about 5 and half hours of flight with more than 120 peoples.
After a briefing, a temporary dorm room was assigned until we can move to the building 203 in near future.
According to David Sullivan, we will have a commute bus at 7:30 AM.
Before we get our notebook computers scanned for security patches, sometime tomorrow, we would have limited internet access.

Best,

MooHyun

Dear,

The hang test for the CREAM-V has completed. Please find the attached log file for details. I will post an update version of complete CSBF integration log file on the black board.

It was started from 5:30 AM (EDT) and finished at 1:00 PM (EDT). Data flow and commanding from the UMD SOC was done also.

After the payload returns to the high bay, the weight without rotator was measured to be 3690 lbs. It is comparable with the last year's 3655 lbs.

Now the payload is in LOS mode and started muon run in flight mode. Will have a long term muon run during weekend together with some remaining works like hsk box test.

On Monday, TDRSS connection run will be done. On Tuesday, the instrument will be packed into a sea container. The same for the GSE crates.

We would like to thank a lot for the supports of all the members who worked hard for this integration possible and successful.

Best, MooHyun
