Woodstock Fire/Rescue and the Bull Valley Police Department responded to the 10,000 Block of Bull Valley Road for a smoke detector activating for no apparent reason.
Responding Units: Woodstock Truck 81, Bull Valley Police Car 149
The problem was due to a faulty battery in the smoke detector.
Bull Valley, Illinois
How long does a passage of a steel ball take?
Here is a scope recording of the detectors signal. Inputs are scanned every 4,096 msec. That is why the recording time is 5 scans or about 20 msec.

The Solenoidal Tracker at RHIC (STAR) is a detector which specializes in tracking the thousands of particles produced by each ion collision at RHIC. Weighing 1,200 tons and as large as a house, STAR is a massive detector. It is used to search for signatures of the form of matter that RHIC was designed to create: the quark-gluon plasma. It is also used to investigate the behavior of matter at high energy densities by making measurements over a large area.

The remains of the rock slide detector switch in Colby Cut at the Roseville Tunnel. The electrical "guts" are gone, all that remains are the mechanical parts. A wire cable would pass through the center of the unit, through the silver cylinder, and connect to the fence. If the fence was disturbed, it would cause the large armature in the unit to pop forward under spring tension and open switch contacts. Any break in the circuitry would cause signals to go red, warning an approaching train of trouble.
These units were manufactured by Union Switch & Signal (US&S) of Pittsburgh PA.

The PHENIX detector at Brookhaven National Laboratory's Relativistic Heavy Ion Collider (RHIC) records many different particles emerging from RHIC collisions, including photons, electrons, muons, and quark-containing particles called hadrons.

STAR is a tracking detector that, like a giant barrel, covers the region around the point where beams of ions and subatomic particles collide. It's capable of tracking and analyzing thousands of particle sprays per second.

Physicist Bill Christie stands behind what's called a carbon fiber inner detector support structure at the Relativistic Heavy Ion Collider’s STAR Detector. Inside this support structure is the beam pipe in which accelerated particles travel prior to collision inside the detector. The support structure allows RHIC physicists to install new particle detection sub systems into the center of the STAR Detector. It will support a device called the Forward GEM Tracker (FGT) and the first engineering prototype of a new Pixel Silicon detector. In the future, it will support the FGT, the complete new Pixel Silicon detector, as well as two more Silicon detectors/technologies: the Intermediate Silicon Tracker (IST) and the Silicon Strip Detector (SSD).
The new silicon detectors will improve many physics measurements for STAR, and allow physicists for the first time to directly measure particles emerging from collisions that carry what is known as "open charm."
The FGT detector allows scientists to measure the positrons or electrons that result from the decay of particles known as W bosons, where these decay products are produced at forward angles. It is used as part of the 500 gigaelectron-volt (GeV) polarized proton-proton physics program.
A sturdy and versatile Sensitive Detector is standard fare for the instrument banks of any well-appointed ray-worker's shop.
Muon Resistive Plate Chamber (RPC-1) in the PHENIX detector at Brookhaven's Relativistic Heavy Ion Collider (RHIC).
PHENIX weighs 4,000 tons and has a dozen detector sub-systems. Three large steel magnets produce high magnetic fields to bend charged particles along curved paths. Tracking chambers record hits along the flight path to measure the curvature and thus determine each particle's momentum. Other detectors identify the particle type and/or measure the particle's energy. Still others record where the collision occurred and determine whether each collision was "head-on" (central), a "near-miss" (peripheral), or something in between.

A close-up of the collision point at the center of the PHENIX detector at Brookhaven's Relativistic Heavy Ion Collider (RHIC). Visible are the copper "nose-cones", the beryllium beam-pipe, and half of the silicon vertex detector and forward silicon vertex detector. The black parts make up the carbon fiber support structure. Vertex trackers are used to reconstruct the trajectories of particles emitted from a collision. The very fine position resolution of these trackers allows the primary collision point to be accurately located.

requesting help to identify which exact scintillator this it - lithium iodide? anybody have a datasheet? thanks. :)
and yeah, it works, it produces a comfortable 8 counts / 10 minutes within the rem ball @ 1300 volts, and is entirely insensitive to beta / gamma.
