How to get ion mobility of DME

Dear experts,

I found the topic of getting ion mobility in this link " How to get the Ion Mobility file - Garfield++ - ROOT Forum (". However, there are no ion mobility of DME, do you know how to get the ion mobility of DME?
Thanks very much for help.

Best regard,

I’m sure @hschindl will be able to help you

Hi, hschindl,is there some way to know the ion mobility of DME applied in the Garfield++?
Thanks very much.

Best regard,

I had a quick look at the standard references

and didn’t find it there, but please have a look yourself if you find data for DME in one of these compilations.

Rob Veenhof found a value of 0.56 cm2/(Vs) for DME+ in DME. This could be a good starting point. You will need to write a new ion mobility file; you could use this one as a template:

Thanks very much for your reply, I check the four literatures again and no specification of DME.
I’ll try your reference value of 0.56 cm2/(Vs) in the simulation, but I worry about some difference of the value for large E/N.
