SRIM is only for Windows and only for Latin alphabet based  Windows. If you have that all you need is just download and look. It is usually used for solids. I don't remember if there is option for gasses. Gasses may have different density. Otherwise Bethe-Bloch equation gives a good approximation.  

there are many monte carlo codes dealing with transport of heavy ions within matter. Geant4 is one of them and if you are only interested in SRIM, a class is dedicated for that. It runs on Linux, Mac OS and windows throug a virtual machine previously installed (VMware). All is opensource and free. Otherwise, many other electromagnetic physis processes are also implemented in Geant4. It's up to you to choose the one you want . They deal with solids but also gases for the ionisation process. You can thus simulate the response of ionisation chamber for example with such a MC toolkit.

If I understand you correctly you want to determine stopping range in others gases for different ions. For this task you can use ''Ion Stopping and Range Tables'' utilities of SRIM software. In ION section you must choose type of ion and set range of primary energy. In Target section choose from Compound Library gas what you need or combine molecule of gas manually (use button ''Add element''). In this case don`t forget marked target as gas and input density. In pictures which I attached you can see an example of stopping range of Hydrogen ions in Air.

PS: sorry my English.

You can see in https://www-nds.iaea.org/stopping/stopping_prog.html

There are link to download some of the free available codes. The ndications are in each webpage.

For gases I suggest the CasP5.2, and consider the option to include capture and loss.

But you can compare the different programs. Take into account that MSTAR and SRIM are semiempirical

Does SRIM work on Windows 10?OR is there any other software that does simulate space environment in Win 10?

YES it does and it should be compatible to all windows versions. 

Can  anyone send me  SRIM software (positron  range in matter)?

thank you all

You can download it from this link

Thank you very much Claudia Montanari. I'll see it.

In SRIM can we use dose (dpa) and irradiation time?

SRIM is compatible with all Windows versions. If one has Wine in Linux it is possible to run SRIM in Linux systems, too. There is a possibility to choose gases as target material. You can choose gases just to click "Compound Dictionary". There are a lot of gas systems.

Arnab Kundu Maybe I'm late to reply, but no. SRIM does not calculate dpa nor time. Only provides the vacancies per ion per angstrom (this variable comes from the binning of the depth you want to analyze). So to convert this result to dpa, you have to calculate how many atoms there are in every bin of your sample and then, divide them by the number of total vacancies produced by the irradiation. In addition, you need to know to fluence, because depending on your dose you will get the total vacancies. To calculate the irradiation time, just plot the dpa/depth in function of ion current, and make some tests. If you need more help regarding this matter please feel free to contact me.

I've been trying to install SRIM on a laptop with windows 10 however, when I click on the installation link on the SRIM site I get "This program cannot be run in DOS mode." followed by pages of symbols. I have tried different versions but all seem to do the same. Any idea why?

Alex Fieldsend Which version of SRIM do you try? SRIM 2013? If installation does not happen plz check the link http://www.srim.org/SRIM/PROBLEMS.htm

@Basanta Kumar Parida thank you for the help. I tried all versions with no fix but using your link I realised the issue was using Google Chrome instead of Internet Explorer which fixed the issue, allowing me to download. Thanks again!

Alex Fieldsend My pleasure.

the compound dictionary doesn't work. I can't select or scroll down, and it then disappears. did anyone face and fix this?

I have the same problem Sarah. I tried uninstalling and installing again but it didn't fix the problem.

Have you tried doing this?

Yeah I just finished doing that. Didn’t fix anything.

I have run SRIM13 on H in Ne with SRIM default parameters, output units 10^-15eVcm^2 and the gas button toggled on and off. There was no problem with getting reasonable output, close to PASS, but there is no difference between solid and gaseous Ne. After all, SRIM relies on empirical evidence, and for H-Ne I am unaware of experimental evidence for a gas-solid difference.

For a more appropriate answer I would have to know what actually the problem is.

Hi Peter,

I was looking at the propagation of hot ions ejecting from a multi-ions plasma plume in a N2 / 5mbar gas background and whether this would effect the range of the ejected ions or not. Apparently (experimentally) the results shown that it does minimises the range from tens of cm to the micron range.

Cheers,

Rad

Dear Rad,

Well, are you sure you use the right lenght unit when asking for SRIM output? If you use cm or microns, SRIM is going to adopt some density for the gas, which need not be the one in your setup. If you ask for 10^-15eVcm^2 or mg/cm^2, you can convert this to your experimental target density.

Maybe I misunderstand you, but I am sure that a discrepancy of three orders of magnitude is not not caused by an error in the SRIM code.

Greetings Peter

SRIM is based primarily on measurements, and there are few measurements in the literature of stopping powers and ranges in gas targets, compared to solids. This is not a serious problem in the energy range above the Bragg peak, but in the so-called velocirty-proportional regime there are problems with the data analysis
