FELICE FTICR
[edit | edit source]Enter some description here, maybe including technical specs
Building the AWG3 program for the FELICE FTICR
[edit | edit source]Measurement procedure
[edit | edit source]- Pulse sequence
* Start GOODAWG3.exe
Open a pulse sequence (C:\felice\awg3-files) … In sequence, check start mode: external start
- Export ASCII MS
Measure a MS in AWG Press open in AWE (Brown MS + red arrow) Right-click maximize AWE (stupid software bug) Convert to magnitude spectrum (pink MS button) File ïƒ Export ïƒ MS as txt (magnitude intensity, spec 30-500) Save
Generate SWIFT pulse Make MS Open to AWE Magenta MS check Click on box to show the excitation (left of time transient) Form a NARROW triangle of boxes over the mass to be ejected ( °F button). Make sure all other buttons are exactly zero. Require extra button? Right click on existing button. Action ïƒ Create Excite pulse ïƒ with SWIFT. Dialogue ok. File ïƒ Save as (same directory blabla.awe) Select excite in AWG: Tab AWE ïƒ select load blabla.awe Sometimes it doesn’t fit: Make the time sequence longer. Set attenuation (100% = OFF)
FELIX/FELICE scan Load FEL compatible sequence (incl FLC settings, undulator & live export) Start AWG scan patch (python program to process data) Configure FELICE settings (double click, enable FLX control) Configure FLC undulator (double click, fill in: 10000/(start-stepsize*('Felice Undulator:Run Count^'-1)) Start at high frequency. Program does NOT stop automatically. Sequence, enable external start (hooked up to D10 64 start trig)
Acquire spectrum via scan processor Open AWG scan patch van Victor Set display min & max to 30 & 1000 Enter gates (name, min, max) Set plot properties to mass spectrum Save configuration file Receive from AWG2 (not 3!) Start in AWG Max 30 sec before undulator should move again
End scan Stop sequence in AWG Stop scan processor
Parameters to write down when scanning FELICE Electron energy in MeV (comparison to other shifts, check whether FLC is working) Macropulse repetition rate Micropulse repetition rate Detuning (spectral width) Scan System (parent & fragment) Which cell (cell 1 = IN focus, cell 4 = OUT of FLC focus) # of shots (indication for required IR irradiation) Wavelength (which vibrations can be observed) Spectrometer (grating & zero ref channel) SWIFT (what is thrown out before IR irradiation) Accumulation time (how many ions are captured in the RLT) # of averages (determines noise level)
Moving the spectrometer box Off & On Supply pyro array Flip manual switch 230V cable, 2x 9 pin cables, LAN cable to NI box, powermeter trig in, pyro Remains attached: power cables, flip mirror & power meter pulse in Cable scheme can be found next to patch panel Pyro (M118) to MF10 to pyro. Interrupt (M114) to MF7 to power meter trig. Always on (M115) to MF4 to AWG.
Power scan Scan: Make sure the flipmirror is down and enable the FELICE gun
Now: Press avg. But software needs to be Quitted/stopped.
Source signal checking
FC2: 150° = IN and 240° = OUT.
QMS as MS (only for continuous sources)
Set external vs manual button to external, and
Set RF only vs resolving button to resolving
In Tempus, select quadrupole
Close and re-open Tempus_DS. Quad is now scanning.
Scope ïƒ Quad Profile Scan
Turn on PMT (make sure no gas is present in RLT)
In-/decrease signal intensity via PMT amplifier and tune file (multiplier & dynode)
