Our Galactic Center has a

Super-Massive Black Hole

AO on 4m, 8m, 10m = opened frontier

High resolution time-lapse “movies” of

stars “slingshotting” about the black hole

TMT will greatly advance this study

Science case for the Chinese TMT

• Finished in 2009.12 by 54 Chinese scientists in 8 areas:

extrasolar planets, fundamental cosmology, star formation, galaxy formation, black holes, near-field cosmology, first objects & reionisation and compact objects.

TMT SAC will meet in Beijing right after the IAU

Laser Prototype Review Closeout

“We appreciate the skill and enthusiasm of the TIPC team,

and their accomplishment in providing a demonstration of a

potential laser for the TMT guide star project.”

“The TIPC Team has demonstrated a laser architecture

that appears to be capable of meeting the TMT

requirements matrix, assuming a potential modification of

the CW/CW-mode-locked requirement. We compliment the

TIPC Team for transporting the laser over a long distance,

in a short period of time, and having it operational again,

quickly, for the review. Demonstrated capabilities include:

589 nm, 17 W, 0.4 GHz BW, M2 = 1.2 “

• Led by Zhongwen Hu and Qingfeng Zhu

(NIAOT) - Kick-off meeting held on March

16, 2011

• Externally reviewed June 21 at NAOC

•Committee members Scott Roberts

(HIA/TMT), Maxim Bocas (Gemini) and

Xiaowei Liu (Peking University)

• Committee impressed by amount of work

done in short time

TMT-India, Project Office, and JPL staff members spent

time together working on M1CS Actuators and Sensors


AO: Deformable Mirror

6x60 Prototype at CILAS Successful tests of actuator lines completed:

– Electrical testing for all 360 actuators:

Average capacitance: ~19.5 nF

Average resistance: ~20 Ohms

– Stroke and hysteresis testing at ambient

and low temperature (-29C):

Stroke > 19 m for the +/- 400V range

(specification 10 m after flattening)

Hysteresis ≤ 5% (specification ≤ 10%)

– Spark tests on spare actuator lines:

Average voltage: ~1980V (vs. 1800V

expected theoretical value)

Manufacturing review scheduled mid June

2012

Prototype testing and study to be completed

by end of September 2012


AO: Deformable Mirror Electronics

Prototype at HIA


A 32-channel prototype board tested at HIA

with dummy loads to represent DM

actuators, based on averaged electrical

parameters provided by CILAS

– All 32 channels meet the specifications for

actuator voltage range, bandwidth and power

consumption

HIA assembling small test box for full

characterization of actuators at CILAS

Next steps:

– More prototyping to validate on-board D/A

converters

– Fabrication of four 96-channel boards with

on-board D/A converters by June 2012

– Test of the CILAS DM 6x60 prototype with

the 96 channel board system during fall 2012

Observatory Software (OSW)

Prototyping in India

Focal Plane Visualization and Asterism Selection Project

(FOVAST)

– Started in November, 2010 with Persistent Systems, LTD in India.

– 6 one month iterations during 2 phases (12/10-3/11, 7/11-10/11).

– Prototype a tool to understand issues related to planning TMT

observations

– Gain experience with remote development in India and agile

development process

Additional work starting soon as part of India

development work:

– CSW Event Service Prototyping - SOW completed,

– Second OSW and 2 TCS-related - SOWs underway.
