Memorandum
for participation in the KSTAR experiment
1.
Scope and requirements for participation in
KSTAR joint experimental research
O KSTAR joint experiment research
-
As the
KSTAR device is utilized as a joint experimental device in which both domestic
and international researchers participate, the purposes of the KSTAR device are
to resolve salient issues of the world fusion community and to raise the
capability of domestic fusion research through it.
-
The KSTAR
device offers the joint researchers all the required circumstances for the
joint experiments to fulfill these purposes.
-
The joint
researchers can participate in experiments and analyze the obtained data.
Furthermore, they can develop, install, and operate equipment such as
diagnostics for creative research.
O Requirements for participation in joint
experimental research
-
Basically,
the KSTAR device supports the collaboration of both domestic and international
researchers as much as possible.
-
It shall
conclude a Memorandum of Understanding (MOU) with each collaborating
institution in order to assure the quality of the experiment operations and the
outcome of research.
-
International
and domestic collaborating institutions can also participate in the KSTAR joint
experiments.
-
Access to
KSTAR network and experimental data will be granted after the Non-Disposal
Agreement (NDA) is submitted to National Fusion Research Institute (NFRI).
O Process of participation in joint experiments
-
The
following two items should be submitted to the NFRI in proposal form:
(1) A detailed plan of the joint experiments; and
(2) Names of participating researchers and a list
of required resources.
-
The KSTAR Experimental
Committee (Project management and TF/WG leaders) shall review the submitted
proposals, coordinate the KSTAR operation schedule, and assign the resources.
If necessary, the committee can request another relevant department to analyze
and review the proposals.
2.
Support to conduct the KSTAR joint
experimental research
O Support from NFRI
-
NFRI
offers all available conveniences to external collaborators for successful
research.
-
Basically,
NFRI pays all the expenses accompanied with operation and management of the
KSTAR device and the equipment.
-
NFRI
properly offers the offices and use of internet and telephones which are needed
for the long-term stay of external collaborating researchers for the
performance of their assignments.
O Support from joint research institutions
-
Responsibility
for payment of personnel expenses such as salary, research expenditures, travel expenses, living expenses, and insurance of the researchers
who participate in the joint experiments belongs to the assigned institution.
-
Basically,
all expenses related to installation and development costs of equipment
accompanying the joint experiments belong to the relevant research funds and
the assigned institution, provided that the expenses concerning the interface
to the KSTAR device and the equipment can be supported by NFRI in accordance
with the mutual agreement.
-
In the
case of computers and software required for joint research, the assigned
institution provides them as a rule, provided that NFRI’s internal resources
can be shared depending on the researcher’s participation or assignment
details.
3.
Safety supervision of KSTAR joint experiments
O Access to KSTAR experimental equipment and
safety supervision
-
During the
visits, the participants of joint experiment research are under an obligation
to fulfill the NFRI regulations for the security of the KSTAR device and safety
supervision.
-
NFRI shall
offer the orientation required for use of KSTAR research equipment such as
electrical, fire, and radiation safety and network security. The external
researchers should participate in this orientation.
-
As a rule,
the researchers and the assigned institution are responsible for all personnel
and/or financial losses derived from carelessness of the joint researchers.
O Quality assurance of the installation of
joint experiment equipment
-
For
installation and utilization of the equipment developed for joint research, it
is necessary to have the review and approval of NFRI’s quality control. The
external researchers are required to cooperate with this review.
-
As a rule,
the equipment installed on KSTAR for joint research is open to other
researchers who participate in KSTAR joint experimental research.
4.
Outcome management of KSTAR joint experimental
research
O Management of experimental data
-
All raw
data from the experiment belong to NFRI in principle.
-
All
experimental data from joint research are available to the other KSTAR joint
researchers.
O Conference presentations and submission of
papers of the results of joint experimental research
-
The right
of a joint researcher to be the first author has to be respected for the
results of KSTAR joint experimental research.
-
The
experimental data and the analyzed results from joint experimental research
should be investigated and approved through NFRI’s courtesy review prior to
public disclosure in addition to the review process of the researcher’s group
and assigned institution.
-
Although
the research is related to the KSTAR device, the research equipment and
analysis resources are mainly offered by external institutions, so that the
relevant courtesy review can be performed by the relevant institution. (Even in
this case, the results from experiments are supposed to be reported to the
KSTAR administrative committee without undue delay.)
O Right of intellectual property derived from
the results of joint experiments
-
In
principle, NFRI has joint ownership on the right of intellectual property such
as patent applications and merchandising of the results from joint experimental
research.
-
The
partition of the right of intellectual property can be coordinated according to
the national R&D regulations and mutual agreement between the relevant
institutions.
