We set the HV to those figured 
out by Paolo: 
s0 1668 
s1 1602
s2 1631
s3 1496
s4 1600


-Run 841
First point of the scan, 
night long run. 
x=10 on scale 2 (that of sector 3)
h=10.44 

-Run 842
Energy scan sector2 (centre)
hv =1631 energy = 471.2

-Run843 eneergy 424.1

-Run844 energy 377.


While we were taking run 846, 
changed the HV to gain in 
dynamic: 
s0 1751
s1 1682
s2 1712
s3 1570
s4 1680

-run 847, single electron 471 MeV
-run 848, single electron 448 MeV, 8900 evts
-run 849, sgle ele 424  MeV, 10600 evts
-run 850,  same,  20 kEvts
-run 851,  400 MeV, 14 kEvt
-run 852,  377 MeV, 15 kEvt

-run 853,  340 MeV,  13400 kEvt
-run 854,  283 MeV,  15200 kEvt
-run 855,  236 MeV,  kEvt
=> Dirty run, too many ele
   Redone in next run.
-run 856,  236  MeV,  kEvt
-run ,      MeV,  kEvt

-run 858 -> to be forgotten


# Begin the scan of the surface of m1

5 minutes runs.

Below, when x<0, means on the 
side of sector 0.

* Run 859 s0
  -(x,h)=-9.75, 15.75
  15 kEvts     
* Run 860 s0
  -(x,h)=-7.25, 15.75
  11200 evts
* Run 861 s0
  -(x,h)=-12.75, 15.75
  15200 evt 

* Run 862 s4
  -(x,h)=15.4, 15.75
    

* Run 863 s4
  -(x,h)=12.86 , 15.75
  14500 evts

* Run 864 s4 
  -(x,h)=18.36, 15.75
  15600 evts


* Run 865 s0 
  -(x,h)=-13.45 , 10.44
  15700 evts
  Very strange ! should be in s0, 
  and seems to be in fact in s1 
  
* Run 866 
  -(x,h)=-18.75, 10.44
  14300 Evts
  Again strange: supposed to be in 
  s0 , and just a bit in s1.

* Run 867 
  -(x,h)=-24, 10.44
  15100
  Very strange, same symptoms as above...

The problem with the 3 previous runs
should ne due to a too high intensity
(more than one electron at a time)...


VERTICAL SCAN

* Run 868 s2
  -(x,h)=2.8 , -0.5
Stopped shortly after start.
Same problem as above...
Linac in electron mode might be the 
reason??


PB solved a few minutes later, 
resume vertical scan

* Run 871 
  -(x,h)=2.8 , -0.5
  12000 evts

* Run 872 
  -(x,h)=2.8 , 1
  14300 evts

* Run 873 
  -(x,h)=2.8 , 3.5
  13600 evts

* Run 874 
  -(x,h)= 2.8, 6
  12200 evts

* Run 875 
  -(x,h)= 2.8, 8.5
  13000
  

-> The above taught us that
    adc3 = sector 4
    adc5 =        2  
    adc2 =        1
    adc4 =        3
    adc0 =        0
