The fission time projection chamber based on GEM technology has the advantages of GEM technology such as high counting rate and high spatial resolution. Therefore, we plan to obtain nuclear charge number, mass number and energy of fission products in a single measurement through fission time projection chamber. This paper mainly discusses the types of working gas, pressure, energy loss and effective charge of fission fragments in the fission time projection chamber based on GEM process. It is found that for the energy loss of light and heavy fission fragments, the distribution width of heavy fission fragments is narrower than that of the light fission fragments. Based on the energy loss of fission fragments in gas chamber, a method to obtain nuclear charge from the effective charge of fission fragments is proposed, which is very important for the development of fission time projection chamber and the multi-parameter measurement of fission products.

Abstract: The fission time projection chamber based on GEM technology has the advantages of GEM technology such as high counting rate and high spatial resolution. Therefore, we plan to obtain nuclear charge number, mass number and energy of fission products in a single measurement through fission time projection chamber. This paper mainly discusses the types of working gas, pressure, energy loss and effective charge of fission fragments in the fission time projection chamber based on GEM process. It is found that for the energy loss of light and heavy fission fragments, the distribution width of heavy fission fragments is narrower than that of the light fission fragments. Based on the energy loss of fission fragments in gas chamber, a method to obtain nuclear charge from the effective charge of fission fragments is proposed, which is very important for the development of fission time projection chamber and the multi-parameter measurement of fission products.
