07.58 E1 pump 794Hz, 2.8A, 2.6e-1 mbar, 3.1e+11/cm2
08.55 E1 pump 785Hz, 2.8A, 2.74e-1 mbar, 4.8e+11/cm2. Therefore, the temperature is changed from 38.8 K to 38.4 K. Values of E1 is changed to E1 pump 782Hz, 2.7A, 2.95e-1 mbar, 6e+11/cm2
09.15 The temperature is further changed from 38.4 K to 38.0 K.  
09.25 Values of E1 is changed to E1 pump  780 Hz,  2.79 A,  3.0 e-1 mbar,  5.87 e+11/cm2
09.35 Values of E1 is changed to E1 pump  779 Hz,  2.79 A,  3.1 e-1 mbar,  2.07 e+11/cm2
09.45 Values of E1 is changed to E1 pump  778 Hz,  2.75 A,  3.0 e-1 mbar,  4.6 e+11/cm2
10.00 Values of E1 is changed to E1 pump   776 Hz,   2.78 A,  3.05 e-1 mbar,  5 e+11/cm2

Intervention by Uli. Reduced H2 regulator to c. 12 bar. Briefly opened exhaust to hasten recovery.
