Select Adaptation Table for Reading |
|
Only possible with an adapted filament |
|||||||||
focus: |
|
type in filament number, see
table ‘focus number FU-mA’ |
|||||||||
U [kV]: |
|
type in a kV value between 40...150kV (or whatever the
limit is) |
|||||||||
|
|
|
|||||||||
Read Previously Selected Adaptation Table |
|
Displays tables of different sizes (kV stage dependent)
after the filament has successfully been adapted. |
|||||||||
If [mA]
: |
|
filament current lowest value highest value |
= = |
standby filament current upper filament current limit + a little bit on top |
|||||||
|
|
table size depends on the filament current mA steps
(individual for every kV stage) |
|||||||||
Ie [uA] : |
|
emission current at the given filament current |
|||||||||
boost time [ms] : |
|
how long it takes to boost up from a specific emission
current (filament temperature) to a higher emission current (higher
temperature) with the boost current = max filament current + 2A
(positive boost) |
|||||||||
blank time [ms] : |
|
how long it takes for the filament to ‘cool down’ from a
specific emission current to a lower emission current (negative boost) |
|||||||||
|
|
to get to a lower mA value the filament current goes down
to 0.5A |
|||||||||
|
|
typically the negative boost time is 2-3 times positive
boost time |
