1 February 2021 - third captivity development
Latest version: weightfield5.17.zip
New to this version:
A few bugs fixed, improved the irradiation routines
-Implemented suggestions to reduce crashes in some linux distributions
- Now the display loads faster due to a reduced number of points used
- weightfield5.14 crashed due to a left over parameter of AC readout, now removed
-
-fixed a bug that forced the timestep to be 0.1 ps
-
-Added the possibility of writing the current output file choosing the time interval [expressed in GS/s, 40 GS/s = 25 ps, 100 GS/s = 10 ps..]
- fixed a big in the saving of graph.
- files are saved always in the directories sensors/data/, even if not written in the file name
Added the electronic description of FAST chip
Fixed a configuration problem with CSA
Changed the name convention: now it takes the full path when loading a specific configuration, for example
./weightfield sensors/data/FBK/W6.dat
-
-Fixed a bug in n-in-n and p-in-p configuration for the LGAD
-
-Fixed a few typos
-
-When you save the data, it also saves the computed fields
-
-When you load a configuration it also loads the computed fields.
-
-Very preliminary version of AC sensor
Tuned the gain in the Massey model
Fixed a bug affecting the gain layer width that
was visible when changing the overall thickness of the sensor
Added support for Silicon Carbide
Fixed a bug in the computation of un-depleted Silicon
Removed multithread for potential calculation.
It caused occasional crashing
Improved calculation for deep implant
Possibility of Acceptor creation saturation
Updated list of sensors
Fixed a bug crashing the program on draw statement
- Few bugs fixed
- Introduced a tau_min for CCE
Possibility of saving a configuration and/or the graphs to file.
The default directories are
sensors/data
sensors/graph
The command line:
./weightfield HPK/B35.dat
loads a 35-micron thick sensor from the folder sensors/data/HPK
- The “load” button allows loading a file
- The “save” file allows saving the parameter to a file
- The red “XXX” button means that the directory where you want to save the file does not exist.
- The red “?” button means you are overwriting an existing file
Added the option of “side MIP”
Moved the gain layer doping type in the section “gain”
Added Ga, Ga+C and B Low diffusion
Fixed a bug that caused crashing on MacOS High Sierra
Added B+C gain layer
Added Proton irradiation
Fixed a bug when asking for very small of R_input impedance
Rewritten the simulation of the BB
Bugs fixed
Selection of NA62 front-end chip
Fixed a bug in charge transfer to CSA
-
-fixed the “rdn” position
-
-Made user selectable the charge in MIP and Laser Uniform
-
-Split the electronics in two frames: CSA, BB, with plots of the resolutions and ToT when running in batch mode
Introduced epi gain layer
A few fixes in the simulation of electronics (one causing crashes)
Overall system speed-up
Now 4 possibilities to choose the gain model:
- van Overstraeten - de Man Model
-
-Massey
-
-Okuto Crowell
-
-Bologna
2 different gain profile: shallow and deep (see link for details)
Moved some initializations away from WFGUI.h
that are incompatible with some Linux compilers
Possibility to choose the gain model:
- van Overstraeten - de Man Model
- Massey
Implemented temperature dependence according to the Canali parametrization
Fixed the effect of B field on the e-h drift
(Thank you Junki!)

-
-fixed a bug that caused crashing when writing out files
-
-changed the CSA simulation according to Rivetti’s CMOS book
-
-Changed the doping profile of the gain layer to match experimental data
-
-Introduced temperature dependance of gain
-
-fixed a few bugs
-
-Fixed a problem connected to the writing to file
- fixed a problem with under-depleted silicon
- fixed a problem in Initial doping removal
- fixed a problem in the p-on-p and p-in-n configurations

-
-Introduced initial Acceptor and Donor removal
-
-Introduced p-doping creation by radiation
-
-variable grid size
-
-fixed a few bugs
User defined beta coefficient in irradiation CCE
Removed L dependence, it is not right yet..
Fixed a bug in the mobility expression
weightfield3.33.zip Do not use!
