Ando Lab Vision 2017

KAGRA

4

• Some are addressed,

some are not

• Worked on actuators,

sensitivity update, green, electronics and cables, O3 configuration and PE, ……

• Y. Enomoto

ALS business MZI simulation with K. Yamamoto PSO Parameter estimation

• K. Nagano

et al.

• K. Komori?

• Not much progress…
• But I still think it is worth a try

Rotating TOBA

5

• T. Shimoda working on cryogenics
• Ching Pin working on Q-value measurements
• K. Komori worked on thermal noise calculations with non-

uniform temperature

Cryogenic TOBA

6

Particle Swarm Optimization!

• Not much progress…
• But, in terms of search for non-standard forces…

Gravitational Inverse Square Law

7

Axion Dark Matter!

• K. Komori working on torsion pendulum
• CSL experiments done by B4
• Good progress in optical levitation experiments
• more laser power
• possibility of

making a curved mirror at ~10 mg scale

• Should be very

close to horizontal restoring force confirmation

• Get high power

laser

Macroscopic Quantum Mechanics

8

• Good progress
• compact turntable with wireless signal extraction
• first monolithic optical cavity integrated with input optics
• reached world best precision in one week
• Observation!
• Bit bigger

(and more stable) turntable

Lorentz Invariance Test

9

• Finish axion paper.
• Finish bKAGRA Phase-1 paper.
• More investigation on sensitivity optimization for parameter

estimation (incorporate detection rate, aLIGO/AdV sensitivity dependence, IM parameters, squeezing, polarization optimization).

• Realistic feasibility study for KAGRA+.
• Virgo visit from June 4 to August 18.
• KAGRA interferometer works from August (or October?).
• Summarize KAGRA lock acquisition scheme, including ALS

and MZI modulation.

• In-vac RF PD and RF QPD.

My Plans 2018

10

• Observe radiation pressure noise with torsion pendulum.
• Horizontal restoring force confirmation for optical levitation.
• Fabricate ~10 mg curved mirror.
• Start observation for Lorentz violation search, summarize

the current setup.

• Some experimental result at cryogenic temperatures.
• Start DECIGO experiment.

• 若手研究者の国際展開事業 started this year
• Never been to Virgo
• Exciting to join Virgo commissioning

towards O3

• After bKAGRA Phase 1, before RSE

Why Virgo, Now?

• The grass is always greener on the other side.
• It is also important to concentrate on your own work.
• But, of course, I’m not saying that we should be narrow-

minded.

• And I know elder people

are narrow-minded.

• You have to be clever

enough to enlighten elder people.
