Please feel free to login (first time will create account) and edit your section. I have put a few placeholders to show how this might work. Immediate needs refers to jobs you would like done by the mine crew as soon as there is any access. I have already communicated the need for SOLO, Gopher, and CoGeNT to keep radon plateout to a minimum. | Please feel free to login (first time will create account) and edit your section.

+ | • Full electrical power was restored to the entire Soudan Laboratory TODAY. | ||
+ | DNR staff and an outside electrical contractor installed a new power cable | ||
+ | between the 22nd and 27th levels. Lab staff then checked to be sure that | ||
+ | all circuits in the lab were shut off. Following this check, power was turned | ||
+ | on to the Lab substation via the new cable. Lab staff then turned on the lights | ||
+ | and HVAC system in the Lab. These systems appear to function normally. | ||
+ | The Lab closed loop cooling system also seems to function normally. | ||
+ | The Lab fire detection system is also functioning and will shut down power | ||
+ | to the lab, in the event of an alarm detection. | ||
+ | |||
+ | • The fiber optic cable has sufficient slack that it will be possible to cut out | ||
+ | the damaged section and re-splice the cable. The splicing contractor will | ||
+ | be working next week. | ||

- | For today, power was limited to the hall containing the CDMS Detector. | + | prepare estimates for general clean up of the lab, including remnants |
- | Dan Bauer checked over CDMS and reported that vacuum was maintained, | + | of the foam and the debris brought |

+ | key personnel on site this coming week, beginning with an on-site pre-construction | ||
+ | meeting on Monday. CNA Engineering has also been hired to provide | ||
+ | geo-technical advice to ECI. A CNA engineer will also be on site this | ||
+ | coming week. A likely arrangement beginning this coming week is that | ||
+ | lab and DNR access to the mine will occur on a first shift, possibly beginning | ||
+ | at 6 am, with ECI shaft work on a second shift, possibly beginning at 2 pm. | ||

- | * There was continued work in the shaft today and a brief entry into the Soudan Lab. | ||
- | |||
- | * Today' | ||
- | |||
- | * The electrical cable between the 27th level substation and the lab was tested and passed with no faults. | ||
- | |||
- | * The foam in the lab has collapsed to the floor, leaving some debris that was swept into the lab by the foam in the area between the entryway and the MINOS Detector. | ||
- | |||
- | * All doors to the lab are now closed at the suggestion of Fermilab engineers. | ||
- | |||
- | * The DNR and University staff have now worked continuously since last Thursday night. There will be no work this weekend, in order to rest the staff for next week. Work will resume on Monday. Steps are being taken now to augment the staff in order to provide longer access to the Lab for cleanup. | ||

- | * Next report will be Monday. |
