Michael is modifying the settings of the electron cooler --&gt; changed beam from bunched to coasting

Merger, Tape server (WS3) checks: DONE, writing ~1036 kB/s, refreshing is fine

Leakage current (WS4): 3.46 uA , stable current

DAQ (WS2): temperature checked,

&nbsp;&nbsp;&nbsp;&nbsp; - clock status:

Clock status test result: Passed 5, Failed 0

Understand status as follows 
Status bit 3 : firmware PLL that creates clocks from external clock not locked 
Status bit 2 : always logic &#39;1&#39; 
Status bit 1 : LMK3200(2) PLL and clock distribution chip not locked to external clock 
Status bit 0 : LMK3200(1) PLL and clock distribution chip not locked to external clock 
If all these bits are not set then the operation of the firmware is unreliable

&nbsp;&nbsp;&nbsp;&nbsp; -&nbsp; adc calibration:

Calibration test result: Passed 5, Failed 0

If any modules fail calibration , check the clock status and open the FADC Align and Control browser page to rerun calibration for that module

&nbsp;&nbsp; - white rabbit check:

&nbsp;&nbsp; &nbsp; Base &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;Current &nbsp;&nbsp; &nbsp;Difference 
aida01 fault &nbsp;&nbsp; &nbsp; 0xc228 : &nbsp;&nbsp; &nbsp; 0xc274 : &nbsp;&nbsp; &nbsp; 76 &nbsp; 
aida02 fault &nbsp;&nbsp; &nbsp; 0x5e98 : &nbsp;&nbsp; &nbsp; 0x5ee0 : &nbsp;&nbsp; &nbsp; 72 &nbsp; 
aida03 fault &nbsp;&nbsp; &nbsp; 0x92d3 : &nbsp;&nbsp; &nbsp; 0x931f : &nbsp;&nbsp; &nbsp; 76 &nbsp; 
aida04 fault &nbsp;&nbsp; &nbsp; 0x7a92 : &nbsp;&nbsp; &nbsp; 0x7ade : &nbsp;&nbsp; &nbsp; 76 &nbsp; 
aida05 fault &nbsp;&nbsp; &nbsp; 0xedc0 : &nbsp;&nbsp; &nbsp; 0xedcc : &nbsp;&nbsp; &nbsp; 12 &nbsp; 
White Rabbit error counter test result: Passed 0, Failed 5

Understand the status reports as follows:- 
Status bit 3 : White Rabbit decoder detected an error in the received data 
Status bit 2 : Firmware registered WR error, no reload of Timestamp 
Status bit 0 : White Rabbit decoder reports uncertain of Timestamp information from WR

&nbsp;

DAQ (WS2): everything ok

Online monitoring (WS 5): done;
