CHAMBER. A room in a house.
     2. It was formerly hold that no freehold estate could be had in a chamber, but it was afterwards ruled otherwise. When a chamber belongs to one person, and the rest of the house with the land is owned by another the two estates are considered as two separate but adjoining dwelling house's. Co. Litt. 48, b; Bro.

Table 2 provides a summary of the methods applied in all of the experiments and illustrates the specific linkages between experiments afforded by ionization chamber (IC) measurements.
Both the Radcal 10X5-1800 ionization chamber and an RTI R100B solid-state detector (sensitive area 1 [cm.sup.2]) were calibrated using the NIST M50 standard beam quality [12].
The BRH suggested a measurement procedure based on 2 concepts, the Computed Tomography Dose Index (CTDI) and the Multiple Scan Average Dose (MSAD), using a single ionization chamber measurement.
The NIST Attix free-air ionization chamber [4] was also used to directly measure the air-attenuation corrections for various sources.
Since the 1960's the NIST pressurized ionization chamber "A" (PIC "A") has been used for two main purposes.

Approximately 60 % of the beam neutrons will be captured in the target; those that scatter through the target walls will be absorbed in a [.sup.6]Li liner surrounding the target vessel, and the remaining 15 % will be transmitted to the ionization chamber at the end of the beamline for diagnostic purposes.
1), the neutrons are initially polarized in [^.x] direction, pass through the front chamber, the [pi]-coil, the back chamber, the analyzer, and into a segmented [.sup.3]He ionization chamber detector [9] that measures the count rate associated with each analyzer state, [N.sub.+] and [N.sub.-] respectively.
