calorimeter

One test had participants exercise while wearing a mask that was connected to a machine called an indirect calorimeter, which measures exhaled carbon dioxide and helps estimate energy usage.

This gold-standard method involves placing a small sample of food or drink inside a device known as a bomb calorimeter.

When an x-ray strikes one of the mercury telluride pixels in the calorimeter, it knocks loose an electron and transfers all its energy to it.

The scattered electrons were detected through their energy loss in a detector called an electromagnetic calorimeter.

Alimena and colleagues wanted to look for particles that live long enough to get stuck in CMS's calorimeter and decay only later.
