Cyclotron Institute TAMU - Radiation Effects Testing Facility
CONTROL SOFTWARE DOWNLOAD PAGE
(Updated on June 22, 2023)
The latest (2023) version of the the control software for the Cyclotron Institute TAMU Radiation Effects Testing Facility (SEUSS)
is included in the ZIP archive that can be downloaded from
https://mare.cyclotron.tamu.edu/vladimir/SeussW.zip (16,664 kb).
After downloading the archive, please extract the files it contains into an EMPTY folder of your choice.
The files can be extracted from the archive using the 7-Zip program (included in Windows operating system)
or using the WinZip program
that can be downloaded from the following URL:
To start the program, run SeussW.exe. You may want to make a shortcut to this file and put it on your
Desktop or in another folder
of your choice. The program should run as intended on any Windows operating system that features Notepad text editor and a web browser.
The screen resolution should be at least 1024 pixels × 768 pixels. Response from the Facility
hardware will be emulated.
The program can be completely removed from the host computer by deleting the folder in which it is installed.
Linked hypertext help pages can be accessed by pointing your browser to file named SeussW.htm located in the installation folder or on-line starting at
A tutorial for new users can be downloaded from the following URL:
https://mare.cyclotron.tamu.edu/vladimir/SEUSS-Tutorial.pdf (368 kb).
- New in 2022: Data from the most-recently finished run are now available in JSON format in file Run_Data.json. The file is located in the Seuss program folder.
- New in 2022: In Set Options the Low flux warning level is re-purposed and renamed to Background flux level. The new parameter has the same effect as the old one did. However,
if the flux measured within one of the regular one-second intervals during a run is below the background level, one second will added to total dead time while the live time will not incremented.
- New in 2022: In Set Run Parameters the Current run number window is replaced with the Next run number window.
- New in 2021: A pdf tutorial for new users is now available (see above).
- New in 2021: The list of K500 beams in the Select Beam window has been updated and made consistent with the list of K500 beams available for radiation testing.
A separate list of K150 beams in the Select Beam window, consistent with the list of K150 heavy-ion beams available for radiation testing,
is now presented when K150 cyclotron is selected. (Change Setup window can be used to choose between the K500 and the K150 cyclotron).
- New in 2021: Atomic mass numbers of the beams on the menu in the Select Beam window are now indicated on the labels. Atomic mass number of the beam is now a part of the beam name
displayed in the Current settings.
- New in 2020: For the standard TAMU ion beams propagating in aluminum, aramica, air, and the most common substrates, the LET and range calculations performed by SeussW have been updated.
The results now agree with those obtained using the SR.exe program distributed in 2019. (The file date is 2012-10-16.).
The supported substrates include Si, GaAs, GaN, SiC, SiGe, InP, and NaI.
Others can be added on request.
An option is available to run these calculations in the legacy mode.
- New in 2020: The range table is more refined and more precise.
The first row of the table reflects the actual setting.
The table caption contains the Bragg-peak parameters.
- New in 2020: The message box on run pause also specifies the accumulated dose in rad.
- New in 2020: The run number increment can be set to an arbitrary positive integer.
- New in 2015: Support for the K150 cyclotron Radiation Testing Beamline has been added
- New in 2014: 24.8 MeV/u Ag has been added to the list of routinely available beams
- New in 2010: 15.0 MeV/u He, 15.0 MeV/u N, 24.8 MeV/u He, 24.8 MeV/u N, and 40.0 MeV/u N have been added to the list of routinely available beams
- New in 2010: Number of supported layers has been increased from 10 (0-9) to 100 (0-99)
- New in 2008: Computerized roll angle control for in-air setup
- On a machine running a 64-bit version of any Windows operating system (XP, Vista, 7 or 8), the Help button (present in the SEUSSW Users control group
and in all the programs that are launched using the buttons from that group) will not work until you copy the file "iexplore.exe" from your Windows folder
to the SEUSS folder. Alternatively, the help pages can be accessed starting at
- This program features ion energy loss calculations that are provided for the convenience of its users.
While the calculations are based on the commonly accepted methods and practices, the author of the program makes
no warranties that the results are accurate and shall not be liable for any damage that may result from the use
of these results.
