time of flight

[′tīm əv ′flīt]
(mechanics)
Elapsed time in seconds from the instant a projectile or other missile leaves a gun or launcher until the instant it strikes or bursts.
(physics)
The elapsed time from the instant a particle leaves a source to the instant it reaches a detector.

The Time of Flight sensor is typically used for collecting depth information, which means, its all about helping you take better portraits.
I have shown that a field-expansion spectrometer with a long drift distance to measure proton time of flight is an attractive approach to measure the electron-neutrino correlation in neutron beta decay.
You could do that for a fixed target, but consider the time of flight. Time of flight is measured in hours when you're doing that.

5, the time of flights for protons that undergo a reversal are much longer than the coincidence time window of approximately 100 [micro]s; therefore, for the selected spectrometer geometry, no reversed protons are detected.

The time of flight information from the CsI detectors allows the [gamma]-ray asymmetry [A.sub.[gamma]] with respect to the neutron spin direction to be deduced as a function of incident neutron energy from the angular distribution: [[d[omega]]/[d[OMEGA]]] = [1/4[eth]] (1 + [A.sub.[gamma]] cos[theta]), where [theta] is the angle between the neutron spin and the direction of emission of the gamma ray.
For each detector pair the resulting time bin physics asymmetries within a sequence were combined by calculating an error weighted average over the time of flight selected for analysis (13 ms through 34 ms).
Key words: neutron beta decay; neutron polarimetry; neutron time of flight; neutron polarization.
In time of flight (TOE) mass separation the higher the ion mass the slower it is moving when it reaches the detector (for a fixed acceleration voltage).
