|1|YZ profile check in order to count total event number.Total number of event is 127982.Definition of dcZ is changed from old analysis. In this moment, dcZ=0 is on system zero point.|
|2|Check Positron window cut. Here, &size(18){Positron window cut defined as (wdcZ^2 + wdcY^2 < 50^2).}; wdcZ and wdcY is calculated as follows: DC_calcz =(-dcu+dcv)*10./sqrt(2.)+(-1.)*(-135+154)/10.*(-dcudcz+dcvdcz)*10./sqrt(2.) |
|3|1st step of Reanalysis of time difference and z difference between mcp and trigger counter. In this moment, I used events which have only 1 hit to mcp and trigger counter.|
|4|2nd step of Reanalysis TDiff and ZDiff.&size(18){Here, I introduce fiducialY cut : fabs(dcY@x=0 )< 25mm.82166 event -> 62811event(Remark NHITTRIG=1 and MCPPOS=1)}; I defined Time difference cut and Z difference cut as shon in the table. Time cut select events electron and positron were detected within 40 ns. Basically, if muonium decayed in outside of target volume, electron and positron were detected supontaneously. &br;by applying this time difference cut, Event that muonium decayed in outside of MCP effective area were strongly suppressed(See Upper- right picture of Zm-Zd).But longitudinal compornent is still remain in this plot.Zdifference cut is just work as reduce such longitudinal compornent. However, longitudinal and 45digree compornent separation getting better.&br; By applying Zcut, Shape of Tm-Td(Time difference of MCP and trigger counter) were changed especially around Tdiff is 0 to 10 ns.Time difference was calculated by TimeMCP- TimeTRIG.|
|5|Reduce considering region with dcZ.&size(18){abs(dcZ) < 25mm, 62881 event ->37055 event(REMARK NHITTRIG=1 and MCPPOS=1)}; I expect that second peak in time difference spectrum get to vanish, but it does not.|
|6|Make sure that: How "far-time event" were generated.Tdiff>100ns|
|7|Tdiff <-20ns opposite side of No6.|
|8|Tdiff <-20ns. and dcZ>0mm. Field cage and downstream structure image were enhanced. Tdiff <0ns event comes from such compornent.|
|9|Tdiff >0ns and Tdiff < 40ns. Expected clear cut for Time difference.|
|10|I'm afraid that the time difference cut is too tight. As see Tm-Td plot,lower-side (>0ns) should be changed to >-20ns, &size(18){if it is not vanished by applying z-diff cut};higher-side, we can see second peak but it doesnt separate as much as I reported in 2nd March. If we treat the second peak are "ghost", higher-side 40ns is changed to ~20ns.&size(18){Now see that: TDifference in requirement of dcZ > 2mm and zdiff cut, as same as previous report. And make sure that How events of "Both fast compornent(~5000ns)" were generated. };|
|11|Under loose timediff cut, fiducial z and y, Z-difference cut are reduced time diff spectrum. The fastest peak(~-20ns) is still remain even though applying fiducial cut. try to see far dcZ region. is it vanish? it should be.|
|12|dcZ > -10mm are required. longitudinal compornent in Tm-Td plot were reduced. In result2 plot, upper left, &size(20){some peaks appeared periodically.};Next, see (Tm+td)vs(Tm-td) plot. |
|13|MCP image requiring positronwindow, dcz,dcy, timediff, zdiff. Separated by time region.|
|14|Time calibration result. calib time deduced from: modtime = mcpresult_timemcp[0]-scinthit_timescint[0]+0.0496597*dcY, calibtime = modtime -4.32261e-03*sdcY. calibtime is calibrated time difference between positron and electron. First peak get thinner, but second peak become bolder.&size(20){ Does it show that origin of 2nd peak is different to the origin of 1st peak?};Fitting method is binned likelihood. range is 7.00 to 13.00 for 1st peak and 18.00 to 32.00 for 2nd peak.|

|1|YZ profile check in order to count total event number.Total number of event is 127982.Definition of dcZ is changed from old analysis. In this moment, dcZ=0 is on system zero point.|
|2|Check Positron window cut. Here, &size(18){Positron window cut defined as (wdcZ^2 + wdcY^2 < 50^2).}; wdcZ and wdcY is calculated as follows: DC_calcz =(-dcu+dcv)*10./sqrt(2.)+(-1.)*(-135+154)/10.*(-dcudcz+dcvdcz)*10./sqrt(2.) |
|3|1st step of Reanalysis of time difference and z difference between mcp and trigger counter. In this moment, I used events which have only 1 hit to mcp and trigger counter.|
|4|2nd step of Reanalysis TDiff and ZDiff.&size(18){Here, I introduce fiducialY cut : fabs(dcY@x=0 )< 25mm.82166 event -> 62811event(Remark NHITTRIG=1 and MCPPOS=1)}; I defined Time difference cut and Z difference cut as shon in the table. Time cut select events electron and positron were detected within 40 ns. Basically, if muonium decayed in outside of target volume, electron and positron were detected supontaneously. &br;by applying this time difference cut, Event that muonium decayed in outside of MCP effective area were strongly suppressed(See Upper- right picture of Zm-Zd).But longitudinal compornent is still remain in this plot.Zdifference cut is just work as reduce such longitudinal compornent. However, longitudinal and 45digree compornent separation getting better.&br; By applying Zcut, Shape of Tm-Td(Time difference of MCP and trigger counter) were changed especially around Tdiff is 0 to 10 ns.Time difference was calculated by TimeMCP- TimeTRIG.|
|5|Reduce considering region with dcZ.&size(18){abs(dcZ) < 25mm, 62881 event ->37055 event(REMARK NHITTRIG=1 and MCPPOS=1)}; I expect that second peak in time difference spectrum get to vanish, but it does not.|
|6|Make sure that: How "far-time event" were generated.Tdiff>100ns|
|7|Tdiff <-20ns opposite side of No6.|
|8|Tdiff <-20ns. and dcZ>0mm. Field cage and downstream structure image were enhanced. Tdiff <0ns event comes from such compornent.|
|9|Tdiff >0ns and Tdiff < 40ns. Expected clear cut for Time difference.|
|10|I'm afraid that the time difference cut is too tight. As see Tm-Td plot,lower-side (>0ns) should be changed to >-20ns, &size(18){if it is not vanished by applying z-diff cut};higher-side, we can see second peak but it doesnt separate as much as I reported in 2nd March. If we treat the second peak are "ghost", higher-side 40ns is changed to ~20ns.&size(18){Now see that: TDifference in requirement of dcZ > 2mm and zdiff cut, as same as previous report. And make sure that How events of "Both fast compornent(~5000ns)" were generated. };|
|11|Under loose timediff cut, fiducial z and y, Z-difference cut are reduced time diff spectrum. The fastest peak(~-20ns) is still remain even though applying fiducial cut. try to see far dcZ region. is it vanish? it should be.|
|12|dcZ > -10mm are required. longitudinal compornent in Tm-Td plot were reduced. In result2 plot, upper left, &size(20){some peaks appeared periodically.};Next, see (Tm+td)vs(Tm-td) plot. |
|13|MCP image requiring positronwindow, dcz,dcy, timediff, zdiff. Separated by time region.|
|14|Time calibration result. calib time deduced from: modtime = mcpresult_timemcp[0]-scinthit_timescint[0]+0.0496597*dcY, calibtime = modtime -4.32261e-03*sdcY. calibtime is calibrated time difference between positron and electron. First peak get thinner, but second peak become bolder.&size(20){ Does it show that origin of 2nd peak is different to the origin of 1st peak?};Fitting method is binned likelihood. range is 7.00 to 13.00 for 1st peak and 18.00 to 32.00 for 2nd peak.|
|15|N/A|
|16|Final result for TDC difference study no1.Time mcp - Time TRIG < -150 region.|
