8. Triple axis spectrometer SIKA
The SIKA’s dance floor consist of 34 solid granite tiles.
The instrument could be used for both thermal cold
neutron TAS. The best energy resolution of 0.0275 meV
(FWHM) is provided at Ei= 2.6 meV

9. Agreement signed off between
ANSTO and NCU.

10. The cold triple axis spectrometer SIKA
We are currently working hard to get background down
to be a world top class cold triple axis spectrometer
Located at ANSTO-Bragg institute
J1 = 0.050 meV
J2 = 0.143 meV
D = 0.163 meV
MnF2

11. Cold Triple axis in the world
LTAS, C11
(stopped, JRR3M)
CTAS
(under commission, HANARO)
SIKA
(User program since 2015 July)
CHINA
(construction, CARR)
PANDA
(Germany FRM-II)
IN14
(Frence ILL)
SIKA will be very important
1. Only one Cold TAS starts user program in Asia-Oceania area soon
2. Neutron flux at sample position is (will be) good
MACS, SPINS
(NIST,NCNR)
CTAX
(HIFR,ORNL)

12. Neutron communities (Potential Users)
Asia-Oseania
Neutron Scattering Association
(the 2nd Conference
took place in Sydney, Australia in 2015.)
CNSS
JSNS
TWNSS
KNBUA
ANBUS(Australia)
• A number of users from Taiwan
• Contribution to Asia- Oceania area
