| Abstract: | Using the package of Garfield, Magboltz and Heed, properties of four helium-based gas mixtures: He/CH_4(60/40), He/C_2H_6(50/50), He/C_3H_8(60/40), He/iC_4H10(80/20) and the drift performance of the small cell drift chamber filled with the above helium-based gas mixtures have been simulated and studied. The performance comparison between two square cells with different cell sizes operated with He/C_3H_8(60/40) is also presented. |
