Subsystem “Lead” Personnel


Subsystem “Lead” Personnel (continued)


SUS

• Unique in that the overall scope is shared between the LIGO Laboratory and the UK Team » Significant interfaces » Efficiently share (precious and limited) expertise » Effectively perform technology transfer from the UK to US» Maximize commonality of design and parts » Organizational structure reflects this separation of scope within the

SUS program

• Overall SUS Project» Single SUS Leader (Dennis Coyne, acting) who manages the entire

SUS project» Single SUS Cognizant Scientist (Norna Robertson) who oversees

the science aspects of the entire SUS project » SUS Cognizant Scientist reports to, and is directed by, the SUS

Leader


SUS (continued)

• In-Lab (SUS/US) Project» SUS/US Leader is Janeen Romie

» Reports to SUS Leader (Dennis Coyne)

» Supported by:– SUS/US Cognizant Scientist (Mark Barton)– SUS/US Cognizant Engineer (Calum Torrie)

• SUS/UK Project:» SUS/UK Overall Project Manager (and formal interface point of

contact for US) is Justin Greenhalgh

» Reports to SUS Leader (Dennis Coyne)

» Supported by:– SUS/UK/UG Project Manager (Caroline Cantley)– SUS/UK/UB Project Manager (Chris Castelli)– UK Science Personnel (Jim Hough, Ken Strain, Mike Cruise)


SUS Decision Tree

• Decisions beyond the SUS Scope are referred to the Systems Engineer (Dennis Coyne)

• Decisions within SUS, but effecting both US and UK projects are made by the SUS Leader (Dennis Coyne) or the SUS Cognizant Scientist (Norna Robertson)

» Technical interchange will occur freely at all levels between the US and UK efforts» Decisions of any significance which could impact either group must be handled by

agreement between the SUS/US Leader (Janeen Romie) and the SUS/UK Leader ("Project Manager”), Justin Greenhalgh

» In the event that there is an impasse between the SUS/US and SUS/UK efforts, then the overall SUS Leader (Dennis Coyne) will make the decision

• Decisions within the scope of either US or UK Project are made by the appropriate “lead” personnel

• In the case of impasse, or conflict, the decision is referred to the next highest authority in the organizational chart

» For example, if there is a disagreement between the SUS/US Leader and the SUS/UK Leader, the issue is brought to the SUS Leader for resolution

» Similarly if there is a disagreement between the SUS Leader and the SUS Cognizant Scientist, then the matter is brought to the Adv. LIGO Project Manager for resolution

COC

• Overall COC Project:» COC Leader (GariLynn Billingsley)» Reports to AdvL Project Manager (Carol Wilkinson)» Supported by COC Cognizant Scientist (Bill Kells)

• COA/Coatings» Due to technical challenges associated with high performance optical

coating development, this aspect of the COC Project has it’s own COC/Coatings Leader (Helena Armandula)

» The COC/Coatings Leader (Helena Armandula) reports to the COC Leader (GariLynn Billingsley)

» The COC/Coatings Leader is supported by the COC/Coatings Cognizant Scientist (Gregg Harry)

• Since virtually all of the engineering for COC is contracted outside of the LIGO Lab, there are no assigned Cognizant Engineers

» The responsibilities generally performed by a cognizant engineer falls to the two Leaders (GariLynn and Helena)
