READ ME Supporting data for "Design and characterisation of a cryogenic linear Paul ion trap forion–neutral reaction studies" - Figure 5: "temperature_2020-12-10.xls" the recording of the temperature over time. Collected on 10/12/2020. The column labelled "Thermo controller" referred to the temperature recorded on the First Stage Cold Shield, in Kelvin. The column labelled "LSD2" referred to the temperature recorded on the Second Stage Cold Shield, in Kelvin. - Figure 7: Recording of the voltage over time by the accelerometer for X, Y, Z axis: "2021-10-21_t=1014_acc1000_cab2_underbelow_100s_pumpON_cryoOFF.tdms" and "2021-10-21_t=1034_acc1000_cab2_underbelow_100s_pumpON_cryoON.tdms" The analysed files are "2021-10-21_t=1014_acc1000_cab2_underbelow_100s_pumpON_cryoOFF_displ.xlsx" and "2021-10-21_t=1034_acc1000_cab2_underbelow_100s_pumpON_cryoON_disp.xlsx" respectively. The figure shows the X axis from both files. - Figure 8: Recording of the voltage over time by the accelerometer for X, Y, Z axis: "2021-09-27_t=1427_acc500_cab1modified_iontrap_100s_pumpoff.tdms" and "2021-10-21_t=1002_acc500_cab1modified_iontrap_100s_pumpON_cryoOFF.tdms" The analysed files are "2021-09-27_t=1427_acc500_cab1modified_iontrap_100s_pumpoff_freq.xlsx" and "2021-10-21_t=1002_acc500_cab1modified_iontrap_100s_pumpON_cryoOFF_freq.xlsx" respectively. The figure shows the X axis from both files. - Figure 9: Recording of the voltage over time by the accelerometer for X, Y, Z axis: "2021-10-21_t=1012_acc500_cab1modified_iontrap_100s_pumpON_cryoOFF.tdms" and "2021-10-21_t=1030_acc500_cab1modified_ion trap_100s_pumpON_cryoON.tdms" The analysed files are "2021-10-21_t=1012_acc500_cab1modified_iontrap_100s_pumpON_cryoOFF_freq.xlsx" and "2021-10-21_t=1030_acc500_cab1modified_ion trap_100s_pumpON_cryoON_freq.xlsx" respectively. The figure shows the X axis from both files. - Figure 10 (bottom): time-of-flight recorded on 13/01/2022 : "WASC1566.xlsx" Ch1 is the trigger chanel Ch4 is the time-of-flight signal The figure is the Ch4 starting at the trigger time = row 84 in the excel file The accelerometer data were recorded and analysed using NI Labview 2021. The main file for the analysis is "\supporting data\Accelerometer labview for analysis\Accelerometer processing data 2.0.vi"; put the .tdms file name and path in "file path"; the name of the file contains the sensitivity of the accelerometer, change the channels sensitivity accordingly. For all files, Channel 1 = X axis, Channel 2 = Y axis, Channel 3 = Z axis.
