Laur,

1.  The Princeton group continued fabrication of the RPC bubbler system and control electronics.

2.  It is now clear that the proposed monitor of isobutane concentration by infrared sensors will not achieve the sensitivity required.  We are therefore in the process of proposing to use gas chromatography in the flammable-gas safety system.

3.  The Daya Bay offline software has been successfully installed on one node of the Princeton HEP cluster.  The installation will be expanded to additional nodes in April.

4. Qing He has contributed to improved simulation of radioactive decays in the AD (docDB 3425).
