Pulses from #50 to #204. Searching for correct magnetic surfaces    

  

 

Abstract :  Details about the conditions and gradual improvements of pulses from #50. The vacuum system has been improved and one new e-gun of only 6mm diametre is assembled. The results, deficiencies or absence of the expected outcomes from each pulse is summarized.

 

 

 

  List of pulses and main parameters

 

See "List of pulses and results in UST_1" in this web for more pulses, some photos and details.

 

Meaning of columns:

# = number of order of the pulse

t = pulse length in seconds

B= approximate value of the magnetic field at axis 

It  = kAmpere-turns in each coil

P = Pressure in the vacuum vessel in milli-Pascals

G.V. : grid voltage for acceleration of electrons in e-beam

Is  = current of electrons in e-beam source (not the current in the beam which is less than "Is" but unknown)

Fil. Volt = voltage at the tungsten filament

 

Contractions:

Simul = The pulse was simulated later to compare with experimental points

p. = point or points

dif = diffused ;  int  = intense ; cl = clear, well defined ; 

1º =  1st   ;  2º  = 2nd  ; 3º = 3rd
