[Hallb] FW: Earthquake

[Hicks, Kenneth]

Dear CLAS Colleagues,

Below is an email I received recently about the situation at J-PARC.  As you can imagine, the news is not good, but not all bad.  In any case, I thought some people might want to know the situation at J-PARC.

Best regards,
Ken

Dear all,

Many of members of J-PARC including Shoji informed us that there seems to be not very serious human damages we suffered from the earthquake, as far as we know.  So this is very good news, under this scale disaster.  At the J-PARC cite, the ground level and its shape seems to change by meter in many points.  It is reported that there are many large-size pipes' broken points.  So we need to take into account that the restoration of J-PARC may take rather long time, though.  It is also requested not to come into any building of J-PARC cite to check apparatus, to avoid any further accident, but some people reported there seems to be not very serious damage.  J-PARC staff will start inspection of the damage.

Another concern we have is the situation of Tohoku university, which locates quite close to the center of the disaster.  They are suffered much from the lack of life-line (electricity, water, and so on), so quite limited information we have.  Although, there are several contacts from Tohoku univ. staff, and we hope they also do not have very serious health damage.

However, the number of killed people in total already reached to 1,000 and more than 10,000 still lost contact.  We are very sorry all difficulty they are facing at.

Sincerely,
Masa Iwasaki

Subject: Re: Damage to J-PARC

Thanks for your concerns.  Yesterday, I was very tired and
wrote a message for the J-PARC buillding and machine alone.

In so far, we have not heard anyone in and around the J-PARC
were injured or dead.  This is the first thing that I worried,
but I was very much relieved by hearing it.  We were lucky
since in the next power generator area outside the campus,
four people were unfortunately dead.

Nishikawa-san and I are discussing how to transport non-
Japanese people in T2K from the area, since although everyone
is fine, the foods, electricity, water, etc. are limited.

Dear J-PARC IAC and A-TAC members

You might be worrying a big earthquake effect in Japan.  At that
time (which was yesterday) I was in Tsukuba.  Today I drove to
Tokai to see J-PARC.  At least, there were no Thunami effect on
J-PARC.  Buildings were very strong so that from outside there
were no significant damages for all buildings, whereas many roads
around the J-PARC were severely damaged.  In Linac and MLP big
gaps of 20-50 cm were detected, primariy since the road is dropped
whereas J-PARC buildings remain as they were.

We designed to tolerate up to 10 meter of Tsunami.  This time,
very fortunately lower than this limit.  Neigbours (north of
J-PARC) had a significan Tsunami effect, though.

The beam was on when this big Earthquake hit.  We immediately
stopped the beam.  There were not hints that magnets fell down.

All roads from KEK to Tokai are damaged, in particular, freeway.
Trains also.  Accesses are therefore very bad.  Today I used
normal road from my house to J-PARC.  It took over 7 hours for
the round trip (usuallly about two or two and a half hours using
freeway)

Since the accelerator is very delicate one, we all would like to
start to study it from Monday, next week.  I do not know how long
it deos take to recover to the original shape.

Dear All,
Sakaba-san of Futaba Co. kindly informed me that:
he was working in the North-Hall of KEK at the earthquake.  North-west
side wall of the Hall was collapsed, but no body including him was
injured.
His colleagues were working in the Hadron-Hall of J-PARC at that time.
They escaped safely with other people. They saw that a part of the
beam line structures and other places such as gas-bottle station were
deformed and/or moved. A part of roads in the J-PARC were also
colapsed. It does not seem that tsunami reached in the hadron hall. It
is still inhibited to access there and more detailed damages are
unclear.
