A bubble chamber is a container filled with a superheated transparent liquid (typically liquid hydrogen) used to identify electrically charged particles moving through it.
In both use and fundamental design, the bubble chamber is comparable to a cloud chamber. Typically, a large cylinder is filled with a substance that has been heated to just below its boiling point.
As particles enter the container, a piston abruptly reduces pressure, causing the liquid to transition into a superheated, metastable phase.
Charged particles produce an ionisation track, around which the liquid evaporates and forms tiny bubbles. The amount of bubbles that surround a track depends on how much energy is lost by each particle.
The Global Bubble chamber Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Bubble Chambers as dark matter particle detectors are taken into consideration. The methods for achieving the improved chamber stability required for this novel application.
For this, a variety of detector methods have been developed. It has been suggested that one quick way to accomplish this is to use liquids that have been mildly heated.
The breakdown of metastability and the appearance of bubbles can occur in these as a result of a concentrated energy deposition from specific particles.
In an SDD, the gel creates a smooth liquid-liquid interface that prevents the constant triggering on surface flaws, gaskets, motes, etc. that is typically seen even in the cleanest bubble chambers.
As a consequence, the lifetime of the superheated state is significantly increased, making a WIMP search feasible.
The use of large, stable bubble chambers has previously been suggested for other rare-event searches (such as those for superheavy elements and nucleon decay), but no concerted effort to prolong the superheated times has been undertaken.
There were no additional safeguards against neutron or radon backgrounds in the chamber, which could hold 30 g of R-115 (C2ClF5) superheated for up to 12 hours at a 1500 m.w.e. deep underground.
This behaviour inspired further investigation and demonstrated the potential of regulating the sources of instability in a bubble chamber.
