There, amid all the memorabilia of a time in America when the good guys were polite singing cowboys who wore white hats and fought fairly and never cussed, is a glass case holding a stuffed Trigger, together with Miss Evans's horse Buttermilk and the couple's German shepherd, Bullet.
The use of the VELO in the LHCb trigger together with its operation in a harsh radiation environment puts additional constraints on the design.
When exploratory behavior ceased, an infrared source producing a calibrated heating beam (diameter 1 mm) was placed under the hind paw and triggered together with a timer.
There is experimental evidence of the existence of a positive effect of Teff cells over Treg population: Treg cells proliferate in response to immunization in vivo [ 28, 40, 53], and in vitro when stimulated with a TCR trigger together with Teff cells (28).
It will act as a cosmic ray trigger, and, together with other ALICE sub-detectors, will provide precise information on cosmic rays with primary energies around 1015 1017eV.
This paper describes the design and preliminary results of the trigger station, together with the physics capabilities of the overall setup.
The triggering hazards considered correspond to earthquakes and extreme rainfall, which are represented by stochastic event sets that provide the spatial distribution of the first two probability moments of the triggering intensity together with the annual occurrence frequency.
The second column shows the propagating wave, both as a pseudo-colored image, and as a plot of wave amplitude vs. distance from the triggering electrode, together with estimates of the space-constants of the decaying waves.
Breath-hold imaging or triggered acquisitions, together with advanced sequence technology (e.g. parallel imaging and rotating phase encoding), make image quality reasonably robust against artefacts induced by respiratory motion and heart action.
Such a luminosity is achieved using a bunch bunch crossing frequency of 40 MHz that will require very fast and low noise signal processing, in order to separate signals from different bunch crossings, very long on-detector buffers to keep the data during the trigger latency together with fast and reliable data links for the off-detector data transmission.
