RSE

VRSE

Variable RSE. Variable optical mode between BRSE and DRSE

BRT

BS

Center

The central part of the IFO, where PRC, SRC and BS are located.

Vertex, Central Part

ETM

End Test Mass. The mirrors suspended at the far ends of the long arm cavities.

End Mirror.

ETMX

End Test Mass of X arm.

ETMY

End Test Mass of Y arm.

IFO

I guess IFO actually means InterFerometer Observatory. But it is used to mean just interferometer, the core part of an interferometric gravitational wave detector.

ITM

Input Test Mass. The mirrors forming the arm cavities suspended close to the vertex.

Front Mirror, Near Mirror.

ITMX

Input Test Mass of X arm

ITMY

Input Test Mass of Y arm

PRC

Power Recycling Cavity

PRM

Power Recycling Mirror

PR2

Name of the folding mirror in the PRC, which is closer to the PRM.

PR3

Name of the folding mirror in the PRC, which is closer to the BS.

SRC

Signal Recycling Cavity. There is a philosophical dispute going on whether to call it SRC or SEC. SEC means Signal Extraction Cavity. Since we are going to operate the LCGT in RSE configuration, probably SEC is a better name.

SEC

SRM

Signal Recycling Mirror. The main argument against the use of SEC/SEM is to use the same terminology as LIGO. Since we will collaborate with LIGO a lot, regardless of we like it or not, it is just easier to use the same words.

SEM

SR2

Name of the folding mirror in the SRC, which is closer to the SRM.

SR3

Name of the folding mirror in the SRC, which is closer to the BS.

Vertex

The central part of the IFO, where PRC, SRC and BS are located.

Center, Central Part

X-arm

The Fabry-Perot arm on the transmission side of the BS. The use of the words listed in the synonyms column is prohibited as it creates great confusion. If we use the name X-arm persistently, people from Kamioka-Kogyo will follow the convention eventually.

In-line arm, 2nd tunnel, Sako-tunnel

Y-arm

The Fabry-Perot arm on the reflection side of the BS. The use of the words listed in the synonyms column is prohibited as it creates great confusion. If we use the name Y-arm persistently, people from Kamioka-Kogyo will follow the convention eventually.

Perpendicular arm, 1st tunnel, Mozumi-tunnel
